Quiz #30 - Question
|
|
| |
| Here’s a quiz from the frozen northlands. |
| |
 |
Photo 30A Habitat: A frozen
lake in rural northern Vermont (Photo 30A). (For those of you into
cross-country skiing, this is at the renowned Craftsbury Outdoor
Center.) Time of year: Early March |
|
 |
Photo 30B I was going around
the perimeter of Great Hosmer Pond on a glorious day of skiing
through a light layer of fresh, dry powder, when I came upon an
animal trail that crossed the expansive frozen lake. As I
approached, I became very interested, as the trail had a distinct
pattern that repeated uninterrupted for as far as I could see (Photo
30B). |

Photo 30C Photo 30C shows a
little more detail, along with a ski track to get a sense of scale. |

Photo 30D Photo 30D is zoomed
in to show the stride. The group length (the length of each group of
4 prints) measured 12 inches. The stride (the distance between the
start of each group of 4 prints) measured 17 inches - precisely the
same with each stride. The trail width was 3 inches. |

Photo 30E Photo 30E is zoomed
in to show one group of 4 tracks. |

 |
Photo 30F Photo 30F is zoomed
in to show the details of the footprints. Because the powder was so
dry, there was not much detail in in the prints, with one exception,
which is shown as a closeup in Photo 30G. This track measured 1¾
inch long by 1 3/8 inch wide. |
