Once you have a little ArcGIS under your belt, you find yourself applying it to the things you do. In late 2018, my son’s BSA troop went to Big Bend National Park, and I captured some GPS track data while we were hiking. When I got home, I merged the track data and some basemaps in ArcMap. Starting from my previous poster layout and adjusting to 8.5×11 was pretty straightforward. Now I’ll have something to work from the next time I need that size.
I really like the National Geographic USA basemap in ArcGIS for this kind of thing. I’d also purchased a physical, waterproof version of the NG map (#225) at the park store. You can get your own copy here. The trails for this area are not as detailed on the 1:133,333 physical map. I still think it’s worth getting.
Our partial hike up the Marufo Vega / Strawhouse trail was fun. We started at the parking lot along the road at the bottom of the map and went North. Where you see the tracks deviate under the E in VALLEY, we missed the Strawhouse Trail’s ascension out of the creek bed. We ended up hiking through a nice slot canyon to the West before we hit our 2.5 mile turnaround point.
On the way back we discovered the correct trail, and returned via the “high road”.
Both tracks were enjoyable for their own unique views.
I’ve got hundreds of great photos from the trip, and I’m considering working on full blog posts for those hikes as time permits.
The main image was assembled in 2018 from several individual aerial photographs taken over 60 years ago. The public domain images are available through a web repository owned by the City of Austin. I learned about them while researching the path of a Boy Scout trail that used to pass through Steiner Ranch. The whole poster idea came about after I had created the mosaic for my research. My wife said “You should print that and put it up at Cups & Cones.” I listen to her most of the time. 😉 You can view it there if you’re in the neighborhood. I had the idea for the “classic” border. I’m open to ideas for other formats/media. Contact me through the e-mail link at to left if you are interested.
Today Marks 69 Years Since The Opening Of The Lone Star Trail
I’ve been researching the trail (off and on) since 2003 when I stumbled across a mysterious metal marker in Austin’s Emma Long Park.
Trail? There wasn’t a trail there as far as I could tell. I had no idea how old the marker was. The marker was just nailed to a tree, way back in the woods. The ground around it was undisturbed, maybe for a decade according to my first underestimate. Yes, this plaque turned out to be older than I imagined.
Back then, I took a picture and moved on. I was hunting something else, a geocache that promised to be somewhere nearby. I set the mystery aside for a while. I posted a photo of the marker with a question about its unknown (to me) history to the internet in 2005. I got the break I needed in 2012 when someone finally associated it with the old Camp Tom Wooten.
Just a quick note: The trail is not to be confused the Lone Star Hiking Trail that winds through the Sam Houston National Forest. This trail is older, and was opened April 23rd, 1950.
Camp Tom Wooten was the big Boy Scout camp near Austin, operating from about 1937-1972. It was out where The Courtyard neighborhood is near the Pennybacker bridge. Eventually, I found Frank Hilton’s Lone Star Trail website, and the hand drawn map shown above. Wow, a real treasure map! Frank’s site is loaded with information. I greatly appreciate his efforts to keep and distribute the history. Since then, I’ve been looking into where the trail went. From the map, I found out that trail winds through the area where we live in Steiner Ranch, and through City Park / Emma Long Park where I found the marker. I’d already been to many of the places it passes through.
Recently, I’ve been using old City of Austin aerial photographs as overlays in the free Google Earth Pro desktop program to find the latitude and longitude of various places and trails I can see in those aerials. When I take the old overlays off, I can see the locations on a modern satellite image. Most of the trail is invisible from the air in 2019. I can see quite a bit in the 1966 aerials. There were less trees then. To date, I have not yet found any of these concrete milestone markers beyond the one for the start that has been moved to the museum (see below). I suspect they were all gathered up when the trail closed.
I’ve also contributed some to Frank’s web page. Namely the modern map (still incomplete) at the bottom of the page and the photo of the aluminum marker.
The trail started at Camp Tom Wooten (now closed and re-developed) and Frank’s website has some pictures of some spots along the trail. I have actually visited the cave shown in those pictures while geocaching.
Continuing on the mapping theme, I wanted to talk about a few tools I use for my mapping activities.
I use an old Garmin eTrex Legend GPS receiver for my geocaching hobby and backwoods exploration. I purchased Garmin’s MapSource Topo in 2004, and I still use it today. The software isn’t updated much anymore, but it reliably moves waypoint and track data to and from my receiver. My map database is still original, but it isn’t a big issue as I don’t tend to use the unit for street navigation. I usually save “raw” field data in .gdb files, and also save a copy where I’ve cleaned up the tracks or edited waypoint symbology and labels. These files can be converted / imported into the programs below.
Google Earth Pro
I know most people know about Google Maps in their on-line or phone app form. Fewer people know about the free, downloadable PC/Mac app called Google Earth Pro. In addition to allowing you to view zoom-able maps of the entire globe, you can also make your own maps to share with others. The features I use are:
Satellite basemaps (recent historical imagery is available)
Track and waypoint overlays from my collected GPS data
Photo overlays of old maps and aerials (zoomed and rotated)
Getting coordinates of features in the overlays and basemaps.
You can also make cool map fly-over videos. It’s an awesome tool and a great place to start learning about making maps.
ArcGIS / ArcMap
Sometimes you need the real deal for mapping. In my case, I found that building a composite aerial map of around 16 photos in Google Earth Pro was bogging down the computer I was using. I also needed to stretch a hand drawn map in a non-uniform way to match the basemap. That task exceeded the capabilities of Google Earth Pro’s zoom and rotate (AKA affine transformation).
Esri’s ArcGIS / ArcMap does all of this work very well. It’s not so easy for casual users without mapping experience, but it’s definitely the way to go for people who are really into this stuff. It lets you stretch maps and aerial images to fit other maps (georeferencing) and uses variable image resolution to speed screen update time. This is the tool that makes most of the print maps you see today. I’ve completed a lot of on Esri’s on-line courses. It’s the next best thing to community college courses on the subject. I find learning this tool to be quite engaging, especially when paired with my interest in local history.
QGIS is another fantastic Geographical Information System program. It’s open source and free to use. It has many of the features of ArcGIS and its components. I did have great success in using the program to get beyond my issues in assembling the previously mentioned composite. On-line training is also readily available. I stopped using the program when I decided to start learning the more mainstream ArcGIS.
If you read my last blog post about Rutledge Spur, you might have noticed I’m into maps and aerial photos. I’m not just sort-of into them. Definitely addicted.
I’m not really sure when it started. I can vividly recall an early memory from when I was 7 years old. My family was moving from Ohio to Arizona and the moving company had supplied us kids with maps and an atlas. I remember following along from the back seat of our Fury III as we got to each town along the way, marking the progress along the highways we traveled. I was already pretty comfortable with maps at the time.
In grade school, a graduate student from the University of Arizona came to try to find out what skills our young minds used for navigating. He brought an aerial photo of the area around the school, and told me to walk us to a spot he was pointing at on the photo. I’d never had access to an aerial that showed our neighborhood before. My first question was “Where do you get these?” I knew it didn’t come from the gas station. I was thrilled to show him how to get there, using my skills counting streets, turns, and houses, but also using visual cues like trees and driveway styles. That guy did not expect a 4th or 5th grader to have that knack yet. He also told me he borrowed the photos from the U of A library. “Mom? Can we go there?” It turned out the graduate student’s borrowing privileges were higher than my elementary student privileges.
I enjoyed learning orienteering, compass, and mapping skills in the Boy Scouts. Gaining access to great topographical maps of the Santa Catalina Mountains fed my addiction, also prompting me to ask where they’d come from. That’s where I found out about Tucson Map and Flag. “Mom? Can we go there?” Alas, time, distance, and money kept me away.
In college, my eclipse chasing buddies were into maps too. At one point my housemate had plastered an entire wall with adjoining sections of the Baja peninsula. By then, I was able to provide transportation on a few trips to the map store.
My interest in aerial observation also stemmed from an interest in flying. I’m a window seat guy with a sore neck. I complteted ground school for becoming a private pilot and also did a few hours of flight time, but job changes kept me from continuing toward that goal at a couple of critical points. I still have lots of old aeronautical charts from those days.
As a defense contractor employee, I learned to use early military GPS receiver data streams at work. When they made accurate GPS available to regular citizens, Geocaching became possible. That was a real marriage of tech and the outdoors. That turned out to be a great match for me. Wow, how great is it that we have all this stuff on our smart phones now?
So, what’s the big draw maps for me? Probably the alternate way of looking at the world around me. Sometimes it’s getting the big picture: “How big is this park?” Sometimes it’s time travel: “What was here before?” Sometimes it’s getting there: “What way do I go?” And sometimes it’s a treasure hunt: “There’s something here I want to see.” The ultimate “treasure” for me is finding out something unexpected or unusual about a place.
I’ve been looking maps and aerial photos of the area near the Marshall Ford / Mansfield Dam because the Lone Star Trail that I’m researching went through the area. In August 2018, I ran across aerial photos of the dam from 1940 on this City of Austin site. Note: You can click on the images of this post to see more detail.
In 1940, the dam was being built. It’s construction was the primary catalyst for change in our area; a huge change allowing Austin to grow and become what it is today.
As I used the Google Earth Pro desktop app to align the old aerial photo to the Google map of the modern roads, I came to realize that a second second “road” that paralleled the current RM 620was not really a road.
It was a railroad! The spur line was built by Brown and Root, Inc. of Austin, and McKenzie Construction Co. of San Antonio. They were also the construction contractors for the dam. I think it was called the Rutledge Spur due to it’s origin at Rutledge Station in Rutledge, TX, but I’m not entirely sure. I had previously read about that very rail line in Carol MacIntosh Sikes‘ book Hudson Bend and the Birth of Lake Travis that I’d borrowed from the library in Lakeway. However, I did not realize that the rail line extended beyond the dam construction area.
The rail line was temporary. It’s gone now. I’d lived in the Steiner Ranch area for 17 years, and never heard anything definitive of it until 2018 when I read Carol’s book. [Well, there were those few nights after we’d first moved here where I thought I heard an old steam train whistle from that direction, but I digress.] The dam was started in 1937, and that is when it was built. It was used to haul rock, steel, and equipment to the site. It’s been gone a long time. Northbound 620 now covers the old bed between Quinlan Park Road and RM 2222.
In the bottom half of the photo above (ca. 1940), you can see the dam under construction on the leftmost side. Note that in 1940, Lake Travis is not filled. In the center bottom (from later 1940), the lake is filled some more, but is not high enough to cover Horseshoe Bend (AKA Sometimes Islands). The railroad line (in orange) follows the Marshall Ford road (in blue) from the right, before deviating into a few turning sections and storage lines. The road does not go over the dam yet, but connects to the current low water crossing bridge. The white and yellow lines are the modern roads. An interesting old dirt road is in purple.
In the top half, you can see that the modern road is straighter, staying south of the current Marshall Ford Road.
Near the Dam Construction Site
To the right of the dam, in the center and north of Marshall Ford road (blue), you can see the cabins used by the building crews. They are arranged in a semicircle that goes out toward the lake. In the center of that, there is another row of cabins on a road extending north. I’d like to know if anyone can find names, maps, layouts, or other history for those camps.
Just past the hollow to the east on the south side of the Colorado River, you can see the clearing where the current Marshal Ford Foodmart sits. To the west of that was the Marshall Ford Bar. That bar burned down, I’m not sure when. Carol details a little about the bar in her book. I believe there were cabins behind these places as well.
Here’s an even closer look at the rail yard near the dam:
The Low Water Crossing road is at the bottom of the picture. The comma shaped area above the rail line will eventually be the huge mound of rocks that are part of the east end of the dam. They probably pulled the tracks out as they started piling up the rocks, because those rocks are now on top of the old railroad beds in that spot.
The grade to the Jollyville Plateau
The railroad (orange) deviated from Marshall Ford Road (blue) to ascend the hill near current Comanche Trail. It went south around the hill that the Steiner Steakhouse now occupies. Traces of the railroad ballast are still visible to the west of the steakhouse in Google Maps aerials. I’d really like to find some historic ground level pictures of the rails in this area. The 1940 aerial also reveals a dirt road “shortcut” in purple. I wonder if that road had a name.
Four Points (Hickmuntown), TX
Here’s a 1940 close-up at the location of the current RM 620 and RM 2222 intersection:
Hickmuntown? No, I’d never heard of it either. But, that’s what they used to call the Four Points area. The railroad line is the straight line from top to bottom in the middle. Note that Bull Creek Road (FM 2222) is paved to the Marshall Ford road (RR 620) the paving only continues south from that point. What about the other dirt road just to the east and heading north from here? Well, technically, you are on it if you are entering/exiting current HEB by the gas station. That road went up to the current 620 and Boulder Lane (the south intersection of the two) before crossing over near 4 Paws at Four Points. It might have also been called the Marshall Ford road. Another possibility is the Anderson Mill Cutoff road. Where’s HEB? Well, it won’t be out here for almost 60 years.
Rutledge Spur between RM 2222 and Anderson Mill Road
The current RM 620 (in yellow on the right above) covers the old railroad path to the current US 183 (formerly SH 29). The section shown above is between RM 2222 in Four Points and Anderson Mill Road near Cedar Park. The red line on the right highlights that old dirt road that existed in 1940. It paralleled and crossed the railroad. It has to be the short-cut described in an article from the Austin American.
Spur Tie-in to Southern Pacific at Rutledge
The spur’s tie-in to the Southern Pacific rail line was in Rutledge, Texas (now part of Austin). The tie-in is almost completely visible at the top right of the 1940 aerial above. That spot is near current Lakeline Mall Drive and Lyndhurst Street, and the current Lakeline Station. There is still a street called Rutledge Spur that terminates at the tie-in point. The crossed roads at the lower left are SH 29 and the road that will eventually be RM 620. I am unaware of the historical name of 620 at that time.

Great news! Today, I got word that my GitHub push request was accepted by Adam at Maniacal Labs, so my code is now integrated in their BiblioPixelAnimations package. I’m hoping that one day, I’ll get to see someone else use the code for their own project.
