Ice Observations for Marquette Area Provided by Marlene
at presque isle NE to horizon, striking midnight blue water intermittent w/
white ice sheets.
Near the island ice appears very thin and transparent in between blocks of
ice which consist of broken up slabs of white ice, thicknesses between 3-8".
this stuff is located to just beyond the end of the breakwall
the current of water from the N is moving quickly, pushing and breaking up
the ice blocks and sheets
between the breakwall of upper harbor and picnic rocks, the water flows
freely out to the distance appox 50' beyond the end of the breakwall, where
the white ice sheets appear neverendding to the horizon
West of the isle, the pressure ridge is at least 80' in length and the ice
mounds, some of which form nifty caves are 8-10' in height, with gentle
slopes. if i had to guesstimate, i'd say a 30 degree angle.
the bay here is socked in with ice, white ,very bumpy, very solid. the ice
continues as this along the west coast extending N a couple hundred feet past
between picnic rocks and mccarty's cove, facing E the pressure ridge there
varies from 30 -50 ' out, not tall at all. again sheets of transparent ice
intermittent w/ sheets and cake mounds of white broken piled up ice chunks.
the flowing water current is beyond the rocks, equidistant to the breakwall.
lower harbor, inside the breakwall, is a sheet of thick white ice, there are
now ice shanties on it. thickness unknown at this time. , and just last
thursday, most of this area was clear ice, looking a lot like a million tons
of broken glass shimmmering in the sun.
ice is nice on a sunny afternoon.
