Annual Lake Michigan Bottom Survey



That's me on board the SS Grayling


I was thrilled to be invited to come aboard the vessel used for the USGS annual bottom survey of the Great Lakes!

This year, the scientists used an underwater camera

Check out the video from this day out on the lake below. This experience will be part of my newest book, 
A 1,000-MILE GREAT LAKE 
ISLAND ADVENTURE, 
which will be released in 2015.
