Gear Reviewer Lincoln works as the climbing ranger in Yosemite National Park, a photographer and writer. His article was recently featured in Patagonia's catalogue about a clean up effort organized in Yosemite last season, and they will be running another this winter about a tragic rescue attempt on El Cap. Lincoln will be taking on issues here dealing with environmental and ethical dilemmas faced by the outdoor adventure world, climbing "ethics" and environmental questions. Lincoln joins us from the US.
