A small portion of the the enormous thistle patch on top of the hill that makes up Raspberry Island (Dan can be seen in the distance). The vegetation between the viewer and Dan is almost solid thistle.

Pitcher plants (Sarracenia purpurrea) grow in many of the bogs in Sylvania. This one is growing along the shore of Louise Lake.
Our search for invasive plants along a lake shore is usually done by 3 people: 2 on land (one close to the shore, the other a littler further inland). Here is Derek walking along the shore of Whitefish Lake while Ben, in the background, is checking among the trees.
The third person is paddling a kayak or canoe. Here Derek is paddling his kayak along the shore of Katherine Lake.
Walking along the shore is sometimes like walking in an enchanting forest with extensive moss carpets and some fallen trees (Drew at Katherine Lake).
Sometimes walking along the shore is pure misery because you have to fight your way through dense, chest-high shrubs that tear the clothing (Drew at Katherine Lake).
Fog on Whitefish Lake.
The fog began to lift as we started our search for thistle on Whitefish Lake.
