Grand Canyon

I found these tracks along the Colorado River.

Who made these tracks? [ View Answer ]


The tracks on the left illustrate the typical bounding stride of mice. This fellow was traveling from lower left to upper right with hind feet swinging around the front feet to make the distinctive 4 X 4 .

The tracks on the right were made by a lizard. A diagonal stride with tail drag is a fairly diagnostic pattern.
