Trail Overview
This is a beautiful short loop in the Sinbad Valley that features petroglyphs and a natural arch. There is a tunnel under I-70 that is currently 9-10 feet high (as of March 2024), although it's off-camber, so that's the smaller measurement. The tunnel is full of sand, so the measurement could change depending on the sand depth. A SxS is easily able to fit through, but a full-size vehicle will need to check the height first. Once across the freeway, the track changes from graded dirt to mostly sandy two-track. There's nothing too challenging, but there are some off-camber sections for those on 4 wheels. There are petroglyphs on a few of the out-and-back trails and there is even a natural arch on the farthest western out-and-back. With lots of fuel and free time, you could really find some amazing sights back here. It's not long or super challenging, but well worth the trip if you have a little free time.

Difficulty
The north of the freeway section is sandy and requires passing under the road in a smaller culvert. Airing down is recommended.
