Welcome back to Musa Masala's Good Trekker, Safe Climber series! As we are concerned with all aspects of mountain safety, we are introducing our first post on safe climbing. Here to help show you the ropes is Michael Wu. Mike is an emergency room physician in San Diego, California, an avid climber and a fan of the sport. He enjoys all aspects of climbing, from bouldering to trad wall climbing. Mike volunteered at the Himalayan Rescue Association (HRA) clinic in Manang, Nepal, in 2014. He worked there with Tatiana, aka Dr. Yak. They recently took a climbing trip to Joshua Tree National Park in California.
