It was cold, thanksgiving weekend 2003, but this route had a really sheltered belay. Our first route at J-Tree, we thought it was 5.6d/5.7a, and the nice gold rock was worth the long drive from Denver. The short approach was especially nice and we noticed very little traffic noise compared to Clear Creek or Boulder Canyons in Colorado.
We also did El Chivo, 5.9a , a route who's steepness, shelter, anchors, and good bolting made pulling on the loose rock very worthwhile.
We carried no guide and mostly got on routes that had visible anchors, good protection, and winter warmth. Turns out our favorites were all Todd Gordon routes. Thank you Todd!
