Learn about the seventh-longest explored cave in the world during a talk by John Lyles at 7 p.m. Tuesday, June 7 at the Los Alamos Nature Center at 2600 Canyon Road.

Lyles will discuss the underground wilderness of Lechuguilla Cave at Carlsbad Caverns National Park. His talk will reveal discoveries in Snowy River passage and Fort Stanton Cave, their exquisite natural resources, and 140 miles of subterranean adventure. This is a free talk organized by the Pajarito Environmental Education Center.

Lyles is an electrical design engineer at Los Alamos National Laboratory. He came to Los Alamos from the east coast, where his interest in caving started in 1975 in Virginia and West Virginia. In addition to spelunking in the mid-Atlantic region, he also explored caves in Missouri and the Ozarks. While spending time underground, he enjoys the solitude and isolation from the hustle of work and life on Earth’s surface. It is an adventure to explore the unknown in Lechuguilla, the second deepest cave in the continental United States.    

This talk is free to attend, and no registration is required. For more information about this and other Pajarito Environmental Education Center (PEEC) programs, visit, email or call 505.662.0460.
