Techy, trials warm up on T-bag and Ratcamp. flowy middle section of the loop with some hard climbs on KRT, 5 Gallon and Buzzard. Finishes with a grin busting descent from the top of the ridge through tight steep rocks, wide open loose sections and velvet singletrack to the parking lot.

    Major erosion (major ruts or slumping, large boulders and roots exposed due to erosion) I've rode in Stonehenge now from the very beginning on the top to the very end where joins the power line. I would say that this is one of the funner basic single tracks. I think it gets its name for Stonehenge for the bottom part which is a little bit rocky. The middle part of Stonehenge has got a deep rut down the middle of it. still I would recommend it.
