Tyler Palmer Tribute

The president of a San Francisco green technology company was killed while skiing at the Homewood Ski Resort near Lake Tahoe, authorities said Monday. Tyler A. Palmer, 37, was found unresponsive at the base of a tree about 1:52 p.m. Sunday, the Placer County Sheriff's Department said.

Skiers found Palmer on the Hobbit Land ski run, head-first in the well of a tree, a depression of loose snow around the trunk. Hobbit Land is a black diamond run, signifying it is for advanced skiers, according to the resort's Web site. Medics tried to revive Palmer, without success, and he was pronounced dead at the scene at 2:28 p.m.

Palmer was the founder and president of GreenMountain Engineering, a design engineering consulting outfit established in 2003 that works with clean-technology companies, according to the firm's Web site.
