“A downhill run just below the hammock on the face of Jumbo and ends when it flows into Plumber's Crack.
— Judd Kleinman
From the hammock, you descend to the west on the Jumbo Ridge
Trail, following the trail through the beautiful landscape of the upper rock garden where you'll see a cairn sitting on top of a large boulder to your right. The trail that drops to the right is Rock n’ Roll and things get steep and loose.
There are 4 or 5 tricky switchbacks on the face of Jumbo before you hit the runout in the basin below. The trail passes through two large boulders leaning against one another (800 bars barely fit!). Shortly after this, you'll come to the intersection with Wapiti Whip
. This next section is also accessible by coming out Plumber's Crack
and taking a left at Wapiti Whip
. This is a favorite section of many locals. It is fast and flowy with some fun little airs.
In general, you'll not even notice where Rock n’ Roll ends and you join with Plumber's Crack
because you are traveling at top speed, hooting, and hollering. That said, use caution at this point because Plumber’s will have two-way traffic.
