Isolation for a peak is the distance to the nearest higher land. These summits tend to be dominant high points of their regions. The number listed for each peak is a distance in miles to the nearest higher ground, not nearest higher summit. All peaks in this grid have had their isolation limit point manually verified.
A red triangle (Δ) before the name of a peak means it has been climbed by Frederick Johnson. Click on the triangle to see the ascent information for that climb.
