VCNP News:

The community is invited to join local geology experts Fraser and Cathy Goff 9 a.m. to 5 p.m. Saturday, Sept. 14 on a PEEC field trip driving through Valles Caldera National Preserve.

Participants will examine the volcanology and geothermal springs of the 1.25-million-year-old Valles Caldera — the world’s type example of a resurgent caldera.

The trip will consist of six stops and take most of the day. Participants will meet promptly at 9 a.m. at the Valles Caldera Visitor Center to board two large vans to travel through the Valle for the tour.

The tour will complete a big circle starting at the Valle Grande Visitor’s Center, driving through the northeastern valley (Valle San Antonio), crossing into the Sulphur Creek drainage, visiting part of the geothermal system and returning to the visitor center along N.M. 4.

Attendees should bring a hat, sunglasses, rain jacket, light boots or sturdy shoes, lunch, water and a camera. Rock collecting is not permitted in the Valles Caldera National Preserve. Several of the stops will involve hiking up steep slopes, across bunch grass and other obstacles.

Registration is required to save a spot on this trip and only five spaces remain. Admission is $48 for PEEC members and $60 for non-members. Sign up at
