"Boromir" is 30' right of "Bridge of Sighs" and ascends a steep face with a thin diagonal crack. Technical face climbing with three cruxes, characterized by thin, precise foot-work yet also by dynamic, technical movement in spots.


West face of Mammoth Rock. As you approach the base of Mammoth, "Proboscis" is the first major line, which starts on the right edge of a small cave. Fifty feet further up-hill is "Bridge of Sighs", which is characterized by two "blobs" in the first 25 feet. Then comes "Boromir", described above.

Really fun climb. One of the cleaner climbs in the area (no loose stuff). Moving past the lieback rail at the third bolt was wild! Dec 14, 2015

Stellar climb. Delicate face climbing with a few dynamic moves thrown in. Dec 27, 2016
