Here are a few pictures from their visit.
|SCA students hard at work.|
|Students computing tree diameter - they first measured the circumference and then divided by pi (3.14).|
|It turned out to be a beautiful sunny day.|
|Downy Yellow Violet adds a pop of color to the forest floor.|
|The long streak continues - every year, students find (and remove) at least one tire from Audubon Woods.|
|One sharp-eyed student spied a pair of morel mushrooms on the forest floor.|
|Wood Frogs are a common sight at Audubon Woods|
|Plants along the trail include ferns and Long-spurred Violets.|
|Most of the students went down to check out the river's edge.|

My favorite picture of the day was one of the first ones I took. While measuring a tree, a group of students noticed a Grey Tree Frog (Hyla versicolor) clinging to its bark.
|Grey Tree Frogs usually blend in well with their surroundings.|
