Started from the TH at 5:20 am. Hiked through the extremely moist forest up to the saddle between Lindsey and the Iron Nipple at 13150'. From there took the class-4 NW ridge to reach the summit at 10:07. The rain and thunder started at 10:20. Stupidly followed some people down the wrong gully resulting in a 2-hour traverse across a steep, loose talus field in a thunderstorm to finally reach the saddle at 1:50 pm. Hiked out in the rain. Returned to the TH around 3:45.
