Bounding trail of Red Squirrel going from bottom to top of photo. Also shown is the Red Fox alternating trail going from left to right.
Single set of Red Squirrel tracks from trail shown in previous photo, trail width of 3 1/4 inches. In deep snow, front and hind tracks merge to form two longer depressions. Can also see the drag marks of front feet leading into and hind feet leading away from the tracks - direction of travel from bottom to top of photo
Striped Skunk - track measuring 2 1/8 inches long by 1 3/8 inches wide. Shows the 3 parts: toes on left, palm pad in middle and heel pad on right.
Same Striped Skunk trail as in previous photo showing part of the typical 2-2 trail pattern.
Den entrance measures 8 inches high by 9 inches wide. Normally used by Woodchuck in summer. Now appears to be in use by Striped Skunk as evidenced by tracks in and out. Later it was taken over by Red Fox.

Single track of Red Fox, 2 inches long and 1 3/8 inches wide. Tape is lined up showing the 2 inch length; refers to the oval shaped depression at base of hole in snow. Obvious drag into and out of the hole should be corrected for when measuring track. Fox is traveling from left to right.
Same Red Fox trail as in previous photo. Important measurement is stride, from toe to toe, which is 16 inches. The stride, narrow trail width (3 inches) and relatively straight trail all point to Red Fox.
Same Meadow Vole trail; note the disappearance of the trail into tunnels in snow.
Typical Meadow Vole trail on top of snow.
Same Meadow Vole trail; trail width = 1 1/4 inches
