We first visited Bottomless Lakes State Park in March 1998 in connection with a student Geology Club spring-break field trip from Emporia State University. This trip to New Mexico was early in our KAP career and was our first use of a radio-controlled camera rig—see film rigs. The camera took 35-mm color-slide film, from which the following examples are scanned.

Water chemistry of the several lakes varies from brackish to saline with 6 to 23 parts per 1000 dissolved solids (Martinez et al. 1998). By comparison, sea water is about 35 parts per 1000 dissolved solids. This salinity is derived from underground solution of salt that led to collapse of sinkholes. This process continues today, as brackish water flows out of Lea Lake via a drainage ditch. Given its relatively deep and clear water, Lea Lake is a popular spot for scuba diving.
