Cumbres and Toltec Geology Train
2022-02-21 | Dr. John Hopkins
We just found out about this year’s Cumbres & Toltec Geology Train adventures in southwest Colorado and northwest New Mexico. Because of the high demand in former years, there are two dates this year, 19 June and 17 September 2022. They’ll both be special opportunities to enjoy some spectacular geology and scenery.
Our very own Peter Barkmann, senior hydrogeologist (emeritus) and Jon Lovekin, our senior engineering geologist—both veteran Geology Train guides—will be on board as geo-docents helping lead an informative and energized day in the high country.
The special train will depart from Antonito, Colorado to traverse spectacular geology along the 64 miles of Cumbres & Toltec line to Chama, New Mexico (or vice-versa). The route features incredible overviews of the Rio Grande Rift, Brazos Uplift, Tusas Mountains and their Precambrian core, the San Luis Basin and San Juan Sag, eruptive evidence of the San Juan Volcanic field, recent glacial deposits, and snapshots of the Jurassic. But more that views, this special train will stop at numerous outcrops and rail cuts along the right of way, to mingle, marvel and collect photographs, samples, and experiences only accessible along the train route.
To accompany the trip, a field-trip guide written especially for the geology train is included in the ticket price, but is also available for purchase from the CGS separately.
Sales are always brisk for these trips, so if you are interested, you’ll have to move quickly!
