Is a mountain on the Olympic Peninsula, and I must climb it, for obvious reason.

Here are the details according to Bivouac.com:

Height: 2181 m (7156 feet)
Name Status: Official

A rugged peak on the east side of the Mount Olympus Massif in northwest Washington State. It’s the highpoint of the divide between Blue and Hoh glaciers. Access is via the Hoh River trail to a campsite called Glacier Meadows, which is located at the base of the Blue Glacier. From the east head of the Blue Glacier, climb a steep gully to reach a col just southwest of the summit. Scramble up the exposed and loose southwest ridge to reach the summit (Class 4).
Name Notes: Named after F. Mathias, a prominent local mountaineer and conversationalist.

Off I go.
