Mt Tantalus (8556') is a peak in the Tantalus Range, north of Squamish, BC.

Nick Elson describes the route:

Tantalus is a rugged, glaciated peak clearly visible from the highway between Squamish and Whistler. Approaching on foot means starting essentially at sea-level and so many ascents begin with the assistance of a helicopter.

Garibaldi is a large alpine lake NNE of Squamish, BC.  This "High Route" circumnavigation of the lake starts and finishes at the Rubble Creek trailhead and includes the summits of Castle Towers, Mt. Carr, The Sphinx and Mt. Price. The route is approximately 54 km with 4,000 metres of elevation gain. Difficulty never exceeding 4th class with substantial glacier travel.

The Issaquah Alps are a low (generally 2000-3000') range of mountains east of Seattle, WA.  They include several popular day hike peaks, such as Mailbox Peak, Mt Si and Mt Teneriffe.  The Issy Alps 50k, 100k and 100M were established by George Orozco as FKT routes for adventurous souls, as reported in Trail Runner Magazine.  A website outlines the routes and the "rules",
