Quite the little group of volunteer history buffs gathered on the south banks of Lady Bird Lake at 9 a.m. The party of nine included a retired judge, an archeologist, an archivist and — to his total delight — a young newcomer to Austin. One lives in La Grange, another in Pearland, but most of us hail from Austin.
We all share in common an interest in Austin history. The informal group first gathered digitally a few weeks ago when Judge Bob Perkins asked about the locations of Colorado River crossings for the Chisholm Trail, which shuttled cattle in the thousands from Texas to Kansas in the late 19th century.
A flood of data — records, photos, maps, overlaid maps — where shared in long email threads. Finally, we decided to find the most likely sites for at least Tinnin Ford, while keeping an eye on the other mapped crossings — Shoal Creek, Congress Avenue, Longhorn Dam, Stones Ford, Comanche Ferry and Montopolis Ferry.
I should take a second to point out that this blog post represents only the barest sketch of the process of nailing down these locations. We’ll return to this material in a few weeks with more rigorous fact checking.
We met at the international hostel right where Tinnin Ford Road dead-ends into Lakeshore Boulevard. After merrily checking maps and sharing references, we headed out the finger of land that leads toward Snake Island. To our right was a former gravel pit. Aerial shots told us that a large mining operation once stood here.
Here, at an ancient cypress, we found what we believed to be the southern entry for Tinnin Ford. One could look across the lake at an angle to see where it would have picked up on Robert Martinez Street Jr. north of the river.
But why were these crossings sometimes called “fords” and at other times “ferries”? “Seasonal changes in the river’s level,” correctly chimed in Austin History Center chief archivist Mike Miller.
We then headed to the other side of the river, across the Longhorn Dam, which bears a historical marker about the trail. After examining several possible low spots on the bank, we settled near another old cypress and guessed this was the other end of the ford.
We still had questions: Was Stones Ford different from Tinnin Ford? Where were the downstream crossings? Below the current Longhorn Dam and Montopolis Bridge, which connect banks that are too high?
A few of us headed downstream to the site of the abandoned Chambers Mill Dam, located on a vast limestone ledge just below the Longhorn Dam. We easily could imagine a low-water crossing here, except that the banks above the flats were too high. A little farther downstream?
Mysteries to be solved later …
