David will be missed and my condolences go out to Nadia, his family and his friends.

Dave was a great man. I have benefited from his craftmanship innumerable times over the years, and could never thank him enough.

My condolences go out to his wife, family, and friends. He will be sorely missed. Blessings.

This is sad. He was very selfless in his years of donated time (fix it skills) to a nonprofit in Laramie. His conservation efforts have helped keep Vedauwoo what it is. In every interaction I had with him he was kind and humble. Condolences to his family.

Dave gave me some of the 1st prototypes of the Alien camming devices, circa 1987, a real quantum leap for us trad climbers at the time. I still use those prototypes today, although the newer devices are way more advanced. His spirit lives on, and his legacy can be seen in the pushing of the envelope in the world of traditional free climbing with the help of his great, "Alien" invention.

3 cheers to the inventor of the Alien! my condolences to family and friends.

My condolences - a man with vision and passion. Thank you David, thank you RIP.

Very sad to hear. After visiting the shop several times in just this past year it never struck me he was especially down or upset by recent events, yet I couldn't help but think it must have weighed on him. I know it would have on me. Just the drama of it all.

His memory will live on in every time I'm totally gripped and somehow manage to perfectly slot a yellow Alien.

Rest in Peace, Dave. Condolences to his friends and especially family. His legacy lives on indeed.

This is very sad. My sympathies to Dave's family and friends. Thanks for your amazing contribution to climbing, Dave.

Sincere sympathies to all his family and friends. Was just thinking I climbed the Bastille Crack yesterday and the first piece on 3 of pitches was a yellow Alien. Peace from above.

Aliens are the most placed pieces of gear on my rack. I hope David's spirit lives on through CCH.
