Olesen Creek Wall

Olesen Creek Wall is a trad-focused crag near Squamish with eight listed routes. The current grade spread is 5.8 to 5.12b, with a mix of single-pitch climbs and longer multipitch lines.

Wiretap is the area’s five-pitch 5.10a route, rising about 115–120 m over pitches of 35, 15, 20, 20, and 25 m. Its listed protection is nuts and double cams from finger sizes through a No. 3 Camalot; a 70 m rope is recommended for the area, with the route descended by four rappels.

Other established lines include Wire Crack, a two-pitch 5.10a variation; Hearsay at 5.10b and 30 m; Eavesdrop at 5.11a; Rumble in the Jungle at 5.8; Float like a Butterfly, Sting like a Bee at 5.11c; and Thriller on the Pillar at 5.10b.

Castle Grayskull is a steep four-pitch 5.12b line of roughly 100–104 m beside Wire Crack. Joel Faubert and Colin Moorhead completed it in 2017; the listed rack runs from finger-size cams to a No. 4 Black Diamond, with doubles from No. .4 to No. 2.

The approach branches uphill near the trail to the bridge over Olesen Creek, before the bridge toward Shannon Falls. A guide describes roughly 10 minutes from the backside trail, including a steep, rough climb to the wall.
