The team begins the ascent of Mather Pass (12,096ft) early in the cold, with Molly & Ethan leading the way. Turning out to be the most technical climb thus far, they take the eastern side up avoiding the avalanche danger on the normal route, however the angle of the pitch is significantly increased. Across rock-climbs and traverses they reach the pass, before descending down the other side with stunning views along the valley. As they cross the snow line they come alongside a raging river, and stop for a swim in the icy waters before drying off in the sun. They spot some deer in the trees, and are pleased to be out of the snow for the moment. Making as much ground as they can towards Muir Pass, the views and the scenery are jaw-droppingly gorgeous. Best day so far, Trail & Errors Episode 65.
