CALL FOR CLIMBING PHOTOS: Did you know these are photos of our members from past competitions!? Due Date 5/15


With Boulder Bash right around the corner we are designing our 2026 photo for our 4th annual summer competition series! We will be drawing up our next design and we have some photos in mind BUT...would love to have you submit your favorite climbing photos.


Guidelines:

- no blurry photos

- try to be the only climber in the photo

- have your whole body in the photo (no cut off hands or feet)

- have photographer stand back so we can get the whole climb (if possible) in the shot.

It is always nice to have a bunch of holds in the photo.
