Yours was not the only weekend adventure. I went to Lake
Vermillion at the
edge of the Boundary Waters in northern MN. This lake has 300
miles of
shoreline and 365 islands. The towns of Embarrass and Tower are
near Lake
Vermillion, and they are the locations where -54 and -60 degree
temperatures have been recorded in recent winters.
I stayed at a friend's cabin at Sunset Rock on a peninsula
called Grassy
Point, and there are a number cabins in the neighborhood on
large lots with
1/4-1/2 mile of shoreline per house. Access is by boat only.
Even the mail
is delivered by boat, as each house has a mailbox at the end of
its dock.
The edge of the peninsula has vertical bluffs created by glacial
plucking
and rounded bluffs created by glacial grinding and polishing,
and each dock
has a stairway that goes up 50 feet or so to a house perched on
top.
We visited several people, some of whom live on their own
island, and all
of them were interested in my estimates of the ages of their
trees, in
addition to forest disturbance history, species of wildflowers,
how to get
more white pine regeneration, etc. Most of the forest in the
area is second
growth white pine and red pine mixed with paper birch and aspen
about
90-100 years old, although there are also a lot of remnants with
older
trees. Ironically some of the oldest trees were in front of the
historic
master loggers cabin, where there is a white pine and some red
pines that
are 250-300 years old.
One uninhabited island about 1/2 mile long is owned by the state
and has a
unique upland white cedar forest that was never logged. The
forest is
multi-aged with trees 100, 200 and 400 years old. There has not
been
reproduction for the last several decades because of deer
browsing on the
seedlings. There was an extremely high diversity of mosses in
the forest,
which grows in high quality soil a few feet deep over 2 billion
year old
Ely Greenstone. The forest reminded me of hemlock forests like
those at
Cook Forest or the Porkies, if you substituted cedar for the
hemlock. Some
of the trees were about 80 feet tall, which is outstanding for
that species.
