NABSQNO 14R-618060-3362520. Technically, this feature is not a natural arch, but it is right on the verge of becoming one. The nascent opening of this soon-to-be waterfall natural bridge is still filled with compacted soil, although water seeps through the mud and under the lintel. When the opening clears, it will have a span of about 15 feet. It is located on Bull Creek, Travis County, Texas. Public access is via the Smith Memorial Trail, which is maintained by the Bull Creek Foundation in cooperation with the City of Austin.
