Limestone bouldering field under the Yamnuska wall. As the name suggests, most of the rock in the field is choss, but the odd high quality boulder can be found here and there. It can be a bit frustrating the first few times, as navigating the boulder field can be confusing, most areas cannot be seen from another area.

It is possible to boulder year round; the sun is good during the warmer days in winter, and there are a lot of shaded problems for the hot summer days.

The potential of this place is barely tapped. For those willing to look, there are a lot of new boulders waiting for sends, as well as undeveloped lines on existing boulders.

Getting There 

Traveling on Highway 1, take exit 114 north on the 1X, Seebee/Exshaw. At highway 40, turn right and travel aprox 1.5km to the "Yamnuska" sign. Turn left and park in the lot. Walk along the road (ignore the foot path) until you reach an open quarry. Take the road as it curves sharply around the quarry. On the left there will be a fence. Look for a distinct path leading into the woods. Walk this path for about 5 minutes and you will come across the Fairy boulder, which is the first boulder in Big Choss.

Start low under the bulge, right hand on a small crimp with a good thumb catch, left hand on an undercling by your feet. Pull off the ground and make a hard slap over the first roof with your left to a sloping side-pull. Bust out right, bumping your way up bad slopers to a hard pinch. Grab the good crimps in the middle of the face. From here its straight up and over the last lip to a rewarding finish.Standing start at the good crimps checks in around V5....[more]   Browse More Classics in International
