The 20th Anniversary of Ultimate Adventure goes big in Alaska! On Day 1 the group departs Wasilla Alaska, airs down, and engages 4x4 to tackle the deep water, bottomless mud, and gooey silt on the trail leading to the Knik Glacier. After getting stuck, suffering some axle and tire carnage, and fixing a few flat tires, Ultimate Adventure heads back to civilization to prepare for UA2019 Day 2.
