ON THE ROCKS PRESENTS

Pedals & Peaks

 August 16, 2025

Trip Leaders: Drew Scherer & Jordan Renner

Join us for the second event in the Pedals & Peaks series at the Grand Hogback Trail System in Rifle, CO! This moderate to challenging trail will take you through stunning terrain nestled against the Grand Hogback, offering a unique opportunity to explore the region's fascinating sedimentary geology. As you ride, we'll discuss key formations such as the Wasatch, Williams Fork, Mancos, and Morrison-Entrada, along with the structural features and basin history of the area. Learn about the economic resources of the Piceance and Uinta Basins, including oil, coal, and natural gas, and how local sedimentology and geomorphology shape the mountain bike trails and riding conditions.

Unlike traditional On-The-Rocks field trips, this event will be more socially focused and feature a broad range of geologic information with less technical depth, making it perfect for those looking to connect with others while enjoying an engaging outdoor experience.

After the ride, we'll enjoy a post-ride lunch and discuss how western slope geology influences the local vineyards and peach orchards. Don’t miss this opportunity to combine geology and mountain biking in one unforgettable experience!
