Jump off the small boulder, which gets lower the closer you are to the Stem Gem boulder. Catch the sloping hueco. A challenging mantle follows.

Stem Gem Mantle

Stem Gem

Start at the entrance of the piss crack behind the Stem Gem boulder. Chimney through the crack, as it narrows into an offwidth roof. Pull the roof and finish up the crack commonly used as a descent from Stem Gem.

A pure mantle on a lone sloper.  This problem continues to get harder all the time due to erosion at the base and feet from Stem Gem ascentionists wearing down the hold.  Pressing this one out in butterfly form just might be the highlight in your mantle career.

Located in a small group of campsites on the Southern end of the Blob formation. Please ask permission for bouldering in occupied campsites.

Stem Gem is the Quintessencial JTree boulder problem, embodying the essence of Joshua Tree climbing: Highly technical and often times perplexing movement across extremely friction dependant, featurless granite. Indeed, this problem has nary a hold on it, the only thing making it climbable is its coarse friction and the undulating nature of the stone.

Getting both feet off the ground on this problem can be an event in itself, bringing ones flexability and stemming prowess to task. Start by stemming up the concave face and then traversing right across a faint/blunt arete. Most continue right and stand on the "bump", however it is possible to avoid the bump and friction direct (v3 friction in itself), continue up the water groove and to the top of the boulder. Jump across boulder to get off.
