June 30 Wizzard Island, Crater Lake National Park Oregon (cont.)
some time for rosy finches. (There is one
record of rosy finches from the island). The lower
portions of the island are wooded whereas the
upper part is more open (steep slopes & scattered
trees). The island is phenologically far ahead of
the mainland. Many flowers are blooming, which
are still buried with snow on the mainland.
Low manzanita bushes, penstemon, Dicentra
and other plants are blooming in large numbers.
White-bark Pine occurs around the rim of the crater.
Mtn. Bluebirds & Golden Mantled Ground Squirrels
are common (as are Mosquitos & Ants). Many
Western Pasqueflower blooming on the east slope
of the upper cone. The large snow patches have
no adjacent meadows, but instead overlies barren
cinders. [illegible] The zonation of
vegetation is the same as the mainland but
more compressed (I think). White-bark Pine occurs
at the top even though it is quite low. Mtn Hemlock
& Shasta Fir occur below this & perhaps lodgepole pine.
It may be that only the upper zones occur here
& [illegible] no compression. The western portion of
the island is a chaos of angular rough chunks of
lava forming a very irregular land contour & no
soil. Three clear pools occur in this area.
Birds on the island include Robin, Red-shafted
Flicker, Oregon Junce, Olive-sided Flycatcher, Wood
