Peñasco to Española - Third-day Supplemental Road Log
— Daniel J. Koning, Gary A. Smith, and Scott B. Aby

This log traverses the northeastern Española Basin and provides an interesting and scenic route for those driving towards Española. The first half of the log examines rift-fill sediments and intra-rift structures within the Peñasco Embayment north of the town of Truchas. Beyond Truchas, several exposures provide opportunity for discussion of stratigraphic, sedimentologic, and structural features within the Tesuque Formation. Additionally, there are good views of geomorphic and structural features along the western front of the Santa Fe Range.
