Dear All, Apr 14, 2015
Some small animal dug narrow pits in the open sections of lawn last
night; the tracks on nearby snow were about 5 cm on either side of a center
line and 45-50 cm apart on each side; i.e. measured from a left or right
track to the next left or right track. The hind foot apparently landed on
top of the fore foot track on a given side. Skunk ?
The deep consolidated snow cover has provided an opportunity to watch
melting as affected by heat conducted from the ground or radiated from an
insolated object.
As one might expect, wooden posts driven into the soil (last summer), or
vertical trees, tend to melt a slightly tapered cone of snow whereas melting
around posts shoved vertically into a snow bank and not in contact with soil
forms a funnel; widest at the surface, often quite short but nearly
symmetrical.
But the greatest melting rate was associated with a fairly large shaving
frame (for shaping wood using a drawknife or spokeshave). The radiator is a
6' nearly horizontal Spruce plank about 51/2" wide and 16" above ground and
a higher sloping superstructure at one end. Beyond the reach of this
radiator there is >2' of compact snow but the ellipsoid centered on this
frame was bare by yesterday afternoon.
