Land OwnerUSFS
Ursus (Latin for bear) is one of the more technical and difficult trails at Jake's Rocks. This trail contains jumps, drops (nearly all rollable), doubles, rock rollers, and wooden bridges.
From the top down, first there is a rock garden into a switchback, then a few jumps, into a rock roller, another switchback, and optional drops on the right hand side. It continues like this the whole way down This trail is more of a technical flow trail, with higher trail speeds than a trail like deerfoot or Bent run.
About halfway down you will see a sign that says "Drops Left", this means that in general the larger drops are to the left side of the main trail, however, they are nearly all rollable. As always do a run to scope out the trail before fully committing to trail features!
The end of the descent is marked by a longer wooden bridge, after this is a mild climb out to the junction with Dew Drop.
This is arguably the best or one of the best trails at Jake's Rocks, enjoy!

Lighting fast. Rock features bridges and cut outs of rocks. Wear your helmet and strap up a little tighter. You can fly or ride your brakes until they are toasted.
DO NOT CLIMB UP TO GET TO ANOTHER TRAIL. yeah I did. But whatever.

Oh-Jeffrey
I saw a 67 year old smoke this trail... like he owned it. Turns out he lives a few miles away. It will will make one grin if you like eastern hills or if your stuck on the eastern half of the states. Well worth the vista views amigos .
We hope you've been enjoying Trailforks!
