This is another sport climb on near vertical, gritty, featured rock that will need some traffic to clean up.

Ascend easy terrain past 3 bolts starting on a micro-flatiron. Then there is a longish reach around the 4th bolt. Dance right (cruxish), up, then left. Note, the 6th bolt leaves you top biner dangling partway over an edge, so I don't recommend falling on the 6th bolt. Perhaps a rounded hanger would allow threading a sling? The terrain eases up and you gain the two bolt anchor.

This route currently leaves one a bit cautious pulling on flakes and trusting edges. Adventure sport climbing.

Note, Claude indicated he felt the route clocks in at 8+. Per Claude "it was named after a small extinct creature that managed to survive for a time during and after the era of the thunder lizards. There's even a picture of what it was thought to look like on Wikipedia." Thanks, Claude!


This is left of Byrontosaurus perhaps 100 feet, past a flake-filled groove, near a moderate-sized tree.


7 bolts, 2 bolt anchor.
