A frozen waterfall we passed on the way up the valley. Kids Club at Immortal Valley, 2022/02/02 On this hike we slid about on a frozen reservoir, hiked past frozen waterfalls up to an ice cave, and then explored snowy trails up in the hills—see 10 photos.

Second waterfall—not so much water here. Third waterfall. The largest waterfall and the ice caves. Snack break in the sun. And another snack break to finish!
