C. melanotus in all habitats save exposed lichen ridges. They are
especially prominent in low center polygons.
1 June
Walked from 10 am to 1930 w/ Lynne Stengel, going from camp (11,40) east
[see map] to (28,42), then south along the river to (19,36)
and finally back to camp. A glorious sunny day through the morning
and into mid afternoon, with temps ~ 40°. High clouds from ~ 1430 to
~ 1830, and then sunny for the remainder. A light NE wind.
We traversed a range of habitats, beginning with the bluffs by the river-
camp spotted w/ Salix spp. The trees, although giants by Barrow standards,
are rarely over 1m high, scrubby, and we get lacking leaves. Catkins
from one sp. (S. lanata) are woolly spread beneath the branches. A few Zoro.
Krusophyta, tranthus sp., & Motacilla flava are all using these habitats. All are
in various stages of display. Walking east we continued along the river bluff
until reaching (15,39), an area which Lynne calls Ground Squirrel Pt. from the abundance
of Spermophilus. Traveling due east from there we entered a region of low wet
funda still largely covered of snow but populated by melanotus, porilla, and mauri.
The low center polygons in this area and particularly to the south from our path are
more similar to Barrow habitats along transect 3 than many other LCP areas
at Meade. Here the minimum elevation is higher + has a drier vegetation type on top
than the low Barrow LCP rims. Vertical relief in these can regularly be over 30cm.
But in this area they are lower, up to 20 cm or so, and the vegetation
is similar to flat appearing or higher Barrow LCP rims. Catenas are often
Caren - Eriophorum s., as at Barrow. This zone strictly as far as X=24,
and also has a series of Caren - Archophila lined lakes. The easternmost ones are
far advanced in melt and were decorated by many (???) Ochtholizania
(>20) Ph. foliarius (see spp spacent). Immediately upon passing beyond the
last of the lakes we had a new vegetation + landform type; the terrain becomes
