Details: "Nodules of Thomsonite can be found in the basaltic lava" according to the Travel Channel's Treasure Wiki Minnesota Page. Go there for more details.
The link for the travel channel's page is broken. Much of the info comes from Bill Reynolds, a columnist with Rock and Gem Magazine. Here is what the link used to say: "General description:Thomsonite is a zeolite mineral with pink, red, and white patterns. It is a very attractive semi-precious gemstone suitable for cutting and polishing.
Visit the folloeing link for Thomsonite rough and jewelry: http://www.thomsonite.com/thomsonite.htm
Handy to bring along: 1. Hammer and chisel 2. Pry bar 3. Bucket 4. Or you can look for pebbles along the Lake Superior Shore I vote for picking up pieces, it is easier than breaking it out of basalt lava.
Helpful notes to newcomers: This is a resort area with many places to stay or vacation. http://grandmarais.com/
See Worrld Wide Museum of Natural Histoty@ http://www.wmnh.com/wmhome.htm"
Directions: To get there, follow the directions on the Travel Channel's Treasure Wiki Minnesota Page. The link doesn't work but said: "How to get there:Nodules of Thomsonite can be found in the basaltic lava flows about 5 miles southwest of Grand Marais, Minnesota or small pebbles collected along the beach.
