Reminder: Rock Quality

As the sun comes out, many of us are eager to return to the crag. Before jumping back on your project, make sure to take rock quality into consideration.

When climbing on sedimentary rock, like the sandstone at Castle Rock or Mount Diablo, it is important to ensure the rock is dry before climbing. Applying too much pressure to damp sedimentary rock can cause holds to break, risking injury and damaging the routes we love.

A good way to check if the climb is dry is by looking at the dirt at the base of the rock. If you dig down six inches and find dry soil, you’re safe to send. If it is still wet, take a rest day!

Igneous rocks, like granite, quartz, and volcanic rock, are safe to climb once the rock surface is dry. But remain mindful of your impact in other ways.

No one likes a slippery approach, but be sure that in avoiding the mud, you stay on trail!

Be a good steward and take care of your local crag. If friends or fellow climbers are considering jumping on a wet climb, respectfully share your assessment and propose some alternatives!
