This benchmark is located .2 miles North of the intersection of FM-770 and FM-834, two Farm-to-Market ("FM") roads in the small town of Daisetta, Texas. The station is ~50ft west of the South-bound shoulder of FM-770, near a gated entrance to the infamous Daisetta sinkhole (a 600ft-wide sinkhole which suddenly developed in 1987 on top of an underlying salt dome).
The benchmark was placed by the
Conrad Blucher Institute for Surveying and Science ("CBI"), a research facility established by Texas A&M University - Corpus Christi to conduct "nearshore" and environmental engineering research (including GIS and Geomatics) throughout the Texas Gulf coastline.
While the BM's inscriptions and stamping "DAS1" and "001" are clearly visible, extensive research on
CBI's website did not reveal any further information about this particular station (which, by the way, is located quite far inland compared to all others maintained by CBI). It is therefore likely an inactive station, once used to measure the sinkhole's ever-increasing expansion during the spring and summer months of 1987.
