Temps in the 70's and sunny -- perfect weather.  Did the loop and sidetrip on the GPX download from the Navigation page - totaled out to about 20 miles and 2,300+ vertical.  If you haven't ever ridden there expect some good climbs, some steep dusty sand surfing descents, some wonderful slickrock, some easy green/blue rolling trails, some double track road climbs/descents and some great views.
Thanks to the creator of the recently updated GeoPDF map. Even though everything is on Trailforks(and might have a different name), the downloadable GeoPDF map is much less confusing if you want to do any of the loops.  There is still no signage anywhere.  A great adventure ride. We saw one biker in the parking lot and no one on the trails the entire day.  If you plan to make a day of it-a water filter might not be a bad idea - you'll see/cross multiple streams and there's the river nearby.
