Ongoing Issues: Yosemite National Park climbing closures and conditions.
Yosemite National Park has yearly closures for Peregrine Falcon Protection March 1- July 15. Always check the Yosemite website Peregrine Closure page at nps.gov/yose/planyourvisit/… for the most current details and park alerts, and to learn more about the peregrine falcon, and how closures help it survive. This page also shares closures and warning due to current fires, smoke, etc.
The southwest face of Hammer Dome is tucked down along Cathedral Creek. Steep knobby face climbing with a mix of hard traditional routes and a few hard sport routes. Routes are single pitch or sometimes have a short second pitch.
This is a quiet place with the classic route Shadow of Doubt.
Mosquito repellent can be handy.
Hammer Dome is along Cathedral Creek, about 1.5 miles downstream from Daff Dome past the approach to Dark Side Dome. Park at the lower Daff Dome parking area near the creek. From the parking area, hike northwest down the short hill to the creek. Cross the creek and follow a very faint trail along the north side of the creek west. About 15 minutes past the very obvious River Wall continue along the creek to Hammer Dome. Approach time is about 30-40 minutes and very enjoyable.
