Topographic relief is significant as the east aspect rises 2,600 feet (793 m) above Royal Creek in less than one mile.

This landform's toponym has not been officially adopted by the U.S. Board on Geographic Names, so the mountain is not labeled as Adelaide Peak on USGS maps.

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

As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow.

[9] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
