The Swamp Angel
Study Plot (SASP) sits in a sheltered 'hollow' at 11,050' (3,368m). The site
derives its name from the historic Swamp Angel mine nearby. SASP consists
of a 6m (20') pipe mast with an extensive array of instruments, a stand-alone
precipitation gauge, and a surrounding 30m x 30m snow profile plot. The SASP
site experiences only very light winds with a winter hourly average wind speed
of less than 1 m/s. The site is generally level, sloping 3 degrees ENE. Signage
advises the general public to avoid approaching the mast or entering the snow
profile plot and cooperation has been excellent. Data is acquired via RF link.
This view is looking east, with the Putney site on the distant dome along
the skyline, near the center of the image.
