Lower Chambers Creek (Sleep Disorder)

A lush, steep, granite technical canyon with exciting rappels when done in the watercourse. Most rappels in the flow happen where the creek spreads out, or can be avoided, so this canyon is likely runnable earlier in the season, or in high-water years. Conditions can be checked at the footbridge at the drop in, but can also be assessed when dropping off an exit vehicle; if the creek looks like something you can walk and scramble in at the exit, the canyon probably goes.

Leave a car at the exit shown on the map (dirt road, though usually accessible by passenger vehicle), and drive a mile down the road to the approach trailhead. The approach is pretty straightforward, just make sure to turn right, crossing a small stream, when the hiking trail branches off the dirt road (100 yards from the parking lot and easy to miss). The approach is a steady uphill climb and has full sun exposure, with very little shade; it can be very hot in the summer. Bring plenty of water. Once you reach a footbridge, that's where the canyon starts. Suit up and jump in the water bypassing the first waterfall (the "siphon"). Checkpoint: Standing in the middle of the footbridge, check the water flow by looking down at the "siphon" and comparing the amount of whitewater with the pictures below. normal water flow (Jul 2014), safe to descend by experienced canyoneers zoomed in version, a stronger flow will produce a larger whitewater area

From the top of the canyon, the rappels start immediately and continue in quick succession. You will likely do between 8-10, depending on conditions. Some trip reports indicate that the longest rappel is only 100’. The original beta stated it was 195’. In July 2023, we estimated it at 160’, with another at 130’. From here, creek walk and boulder hop your way down the creek to your car. There are one or two areas with tricky down climbs, where some people may need assistance.
