The interactive map below is initially centered on the target summit (The Thumb), but may be scrolled around by simply grabbing hold of the map image with the mouse and dragging. The controls at the top may also be used to pan around, adjust magnification, and select different map types. Clicking a peak marker displays a window containing information about the summit. Even more information about The Thumb appears in the Peak Details section just below the map.

The Thumb map too small for you? Go big or go home.
