Before we arose, Stan went out to check on my conclusion based on the drone survey. He confirmed its findings.
Therefore when ready we set out for the trailhead. The way was dark still and would be until the sun crested the cliff side. It seems Stan could not hike at our pace and was constantly running forward, then back to us.
We were midway on our trek when he returned from a similar foray with the report that the way ahead was impassable. Lyle launched his drone to check the extent of the problem.
A cliff wall section is down. My companions declined to swim around. Instead, Stan recommended we try the lake’s other side. We return to camp.
