Thunderslap

I believe this route is technically a harder variation to the Irregular Arete. Start low on the upstream end of the River Boulder on the two jugs on either side of the bulge. Get low and difficult to see feet, or a heel/toe hook around the right edge. Manage your way up the bulge with a couple powerful throws and slaps up the arete feature to your right.

This problem is an eliminate and does not use the face to the left of the bulge and stays on the bulge itself the entire time. If you use the face then you climbed the original problem, Irregular Arete V1.

To get to the river boulder, take the first left in the park, park right away. Hike up the street until you get to a trail on the right. Walk down the stairs and follow the trail down river until you see an obvious boulder on the right about 100 feet down the trail. The problem is on the upriver (east?) side of the River Boulder and follows the bulge straight up.

The low crux can be protected easily with one pad but it would have been nice to have another and a spotter for the top out.
