Hall Natural Area

Several deeply glaciated northeast-facing cirques are present, with steep headwalls and flats or lakes at their floors.

Much of the lower elevation area is stepped topography resulting from differential erosion along jointing planes in the granitic bedrock.

[1] The Research Natural Area (RNA) program is a nationwide system created to protect a network of federally administered public lands for the primary purposes of maintaining biological diversity, providing baseline ecological information, and encouraging research and university natural history education.

The Carnegie Institution of Washington’s studies on genotype-environment interactions made much use of the transplant gardens at the south end of the Natural Area.

Since then, other researchers have used the area, studying social organization of Belding ground squirrels, dynamics of wind-blown detritus in snow banks, and community structuring of subalpine forest birds.
