Just
below the 7,000 foot crest of Park Ridge, the trail passes a
series of perennial icefields. These represent the remnants of
much larger glaciers that once swept down the north face of Park
Butte, and created the valleys and lakes below. Though these
icefields are gradually shrinking as the climate warms, each
winter season brings 20-30 feet of new snowpack, replenishing
the icefields. |
