Most deaths on a peak from falls:
Long's (no contest.) Roughly 35 deaths from falls alone. Note: The first time I ascended Long's I happened upon a climber who had passed away the day before from a fall on the homestretch. Though campers at the Boulderfield had been told there would be an early evacuation, my partner and I were summiting around 6:30AM and stumbled across him. No one else came up for over two hours. As I went to check him for ID, I found evidence that he had been worked on by medical personell and became aware that someone knew he was there. As I summited, a helicopter landed next to me and a ranger came up to me and asked, " Have you seen anything........hmmmmm.......Unusual?"
Deaths on every peak in a range : Crappy Question , Sorry!
I was going for Sangre de Christos. However, I was thinking of Culebra as part of a "Culebra Range" rather than the "Culebra Group." Also, I was considering the death of Douglas Beach (who fell to his death down Kirk's Couloir) as a death on Challenger, but it seems more sources are calling it a death on Kit Carson. Either way, a few years ago an SNR professional told me that, at that time, the Custer County SNR has a higher body recovery to mobilizations ratio than any county in the state.
August 9, 1992 : Ronald Palmer suffered a fatal fall 1,000 down the West Face while traversing the Knife Edge.
August 19, 1997: Derick Eckstrom had a fatal fall 1,100 feet down the East side of the Knife Edge when a handhold came loose.
To end the topic: There has been a 14er death by gunshot. On August 28, 1889 a teenage boy (surname Stryker) stumbled on the Long's peak homestretch and the loaded handgun in his pocket discharged, striking him in the neck. He bled to death while his father, two uncles, and guide Carlyle Lamb looked on. They may have been armed for a myriad of reasons, but it is known that his party fired their weapons into the air while celebrating their sucessful summit.

Couldn't we all use 50 years of humble growth?
