This was just posted on the Huautla Cave Diving Expedition Facebook page: Earlier this week the dive team returned from beyond the sump after spending one week camping and exploring. After compiling survey data we can report that Sistema Huautla is now 1,545m deep. Sump 9 was pushed to a length of 410m and depth of 81m on the final dive. In addition to this 1,774m of new dry passage was surveyed although no bypass to Sump 9 could be located. This makes the total extra survey length 2,184m. The new depth of Sistema Huautla makes it the deepest cave in the Western hemisphere. Bill Steele
