Drew Brayshaw grew up on the slopes of the North Shore Mountains. Raised as a hiker by his father, he started scrambling as a teenager while bouldering on the granite sea cliffs at Lighthouse Park and Whytecliffe. He learned to climb with the Varsity Outdoor Club at UBC in the early 1990s. A resident of Chilliwack since 2000, he works as an environmental consultant when not in the mountains.

Inspired by the exploits of local mountaineers recorded in Bruce Fairley’s guidebook and the Canadian Alpine Journal, such as Don Serl, Fred Beckey, John Clarke, and Dick Culbert, he has sought out first ascents for the last 20 years. He pursues all types, from boulder problems and rock climbs to waterfall ice routes and technical alpine climbs on the peaks of the Cascades and Coast Mountains. Since 1994, he has made several dozen alpine first ascents, including notable routes like Mars Western on the Old Settler, the North Couloir of Mt Rexford, the Beautiful Nightmare on Plinth Peak, the Paymaster Couloir on Crazy Peak, and Lillarete on Mt Athelstan. In winter he has added several dozen new ice climbs to the Fraser Valley, Fraser Canyon, Hope-Princeton, and Lillooet areas.

Motivated by the limitations of the internet and the long hiatus since any comprehensive guidebook to southwest BC mountains was published, he has been researching and working towards the creation of an accurate and thorough modern climbing guide to his much-loved local mountains since 2012.
