  • Description 

    I labelled this area Brimstone for the sake of synchronizing with Jamie's guidebook, but Lower Upper is a more practical name as this is the lowest area in Upper Chaos, and Brimstone is a relatively obscure problem (although it looks great). Boulders rest in a pleasant, green meadow on the edge of the talus field. Established boulders include (but are not limited to) Brimstone, V6; Triple Threat Arete, V10; and Rocky Mountain Beaver Fever, highball V1.

    Getting There 

    It is directly across the lake from Lower Chaos. Approach as you normally would on the climber's trail to upper, and bail off the trail before it starts climbing into Upper Chaos. The area has a few established problems including Triple Threat Arete, V10, and Brimstone, V6. See Emerson's guidebook for more info on this underappreciated sector.

    Rocky Mountain Beaver Fever was named for all the fat, tailless beavers you see running around the park. At least that's what the tourists told us they were.RMBF climbs an inviting and tall, east face right on the edge of the talus and maybe 10-20 meters north from triple threat arete....[more]   Browse More Classics in Colorado
