It is the highest point in the Tatoosh Wilderness,[1] a protected area which is managed by Gifford Pinchot National Forest.

Tatoosh Peak is located in the marine west coast climate zone of western North America.

As a result, the west side of the Cascades experiences high precipitation, especially during the winter months in the form of snowfall.

[3] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below 0 °F (−18 °C) or above 80 °F (27 °C).

[4] Author Martha Hardy wrote about her experiences keeping watch at the fire lookout in her 1947 book, Tatoosh.
