if your into geology this will make your eyes water!
you can zoom in on the detail right to your house.mine in South Minneapolis
is on sandstone.i checked out my folks home in NY and the mountain top
base I was stationed on in Korea.
the BW and Q are in the sort of detail where you can click on a shoreline and
then just up a ways find another type of rock.
use this like Google earth which is the base and different colors,many-many of them,
to represent the bed rock.

cyclones30: "I can spend hours on sites like that. My wife has a couple degrees in soils, but I love maps.
I always like the target in Iowa and oddities I've been to. Mounds in southern WI, Sioux quartzite, etc"
what is up with the target in iowa? impact crater?
Blue mound state park in luverne is interesting how it appears to be right in a transition zone to another rock type. Also ive learned that The baraboo quartzite at devils lake in baraboo wisconsin is not identical to the sioux quartzite of blue mound.
thanks for sharing!

That's cool. I'd like to take it into the BWCA and see if my untrained eyes can spot differences. For instance, part of the BWCA is on the Duluth Complex. It would be interesting to see if one can spot the boundary. Or I see "Lac Lacroix pink granite" in the western BWCA). I've noticed that pink granite on trips. Cool to see that on maps.

"Said one of these men, long past seventy years of age: 'I could carry, paddle, walk and sing with any man I ever saw. I have been twenty-four years a canoe man, and forty-one years in service; no portage was ever too long for me. Fifty songs could I sing. I have saved the lives of ten voyageurs. Have had twelve wives and six running dogs. I spent all my money in pleasure. Were I young again, I should spend my life the same way over. There is no life so happy as a voyageur's life!'"

Really interesting thanks! The lake I live on is cut in half (or thirds) by two different formations. Really cool to see how it changes, now will have to look for differences outside.
Wherever there is a channel for water, there is a road for the canoe. -Thoreau
