This website assembles information from all over the world, using the web and its free exchange procedures. There is no financial profit from this, but we hope there is an educational profit and that this can lead to assorted profits for the user. Using the web in this way works because many allow free distribution and educational use of unique materials.

Most of the photographs on this website were taken by myself, but others have been used with credit from free-sharing government sources such as USGS, NASA, NOAA, NPS, Michigan DEQ. Many useful aerial and satellite views were provided through the web by Google Earth, Apple Maps, Superior Shoreviewer, Great Lakes Shoreviewer and the US Army. Neil Harri’s excellent aerial views were used to show some unique perspectives. Academic sources, including universities, colleges and their faculty and students, through their websites and writings including wikipedia, were also used.

Geological Field trips helped to trigger interpretive work like this.  The most recent Isle Royale venture in May 2013 was pivotal. Lori Witting did the planning and financing issues for the Isle Royale trip. Mark Klawiter planned food and field logistics. Erika Vye and Bob Barron helped with numerous details. Guy Meadows and Marty Auer of the MTU Great Lakes Center helped make the trip a success.

Rolf Peterson generously spent two days with us, and greatly enriched our knowledge of Isle Royale. I would like to thank Lucas Westcott, Liz Valencia and Greg Bickings of Isle Royale National Park for permitting and helping plan this field trip.  Steve Roblee was an eager boat pilot. Kim Alexander helped with facilities of the Rock Harbor Lodge.  N King Huber provided us with a complete set of his many publications about Isle Royale and also with lots of cheerful encouragement. Jim Paces, Tony Longo, and Rick Wunderman provided me with a lot of insight on the volcanic geology of Isle Royale. Kate Witthuhn-Rolf supplied some unpublished data. Discussions with Bruce Marsh, Ian Campbell and Angus Hellawell about solidification helped me to understand a little better what may have been going on inside Isle Royale's lava flows. Seth De Pasqual at IRNP provided LIDAR maps for the guide and explanations of them. Evgeniy Kulakov worked on the paleomagnetic information for us. George Robinson helped find some great mineral specimens to illustrate the zeolite facies amygdaloids, and John Jaszsak helped with photographing them.

There are so many crucial words and illustrations that are needed, and I tried to use as many as I could. A few of the rich old sources are shown in the GeoPeople page.  Here are some of the names of people I personally met who helped:  Jim Belote, Ted Bornhorst, Bill Cannon, Henry Cornwall, Jim DeGraff, Doug Elmore, Fraser Goff,  John Green, Alex Guth, Ken Hon, Wayne Jolly, Susanne Nicholson, Dick Ojakangas, Lauri Pesonen, Anthony Philpotts, Josh Richardson, Suzanne Schmidt, Steve Self, Dick Stoiber, George Walker, Walter White.  Others are in the Bibliography.

Janet Woerner did thorough proofreading and prepared the Bibliography of the website--a huge and very discouraging job. She also shared many suggestions about what was missing or nonsensical in early versions of the website--and many of these were at least in part corrected, thanks to her.

Erika Vye provided consistent help and strong interest in this effort.  She did many supportive tasks. Joan Chadde and Lloyd Wescott of the GLRC accepted administrative responsibility for some field trips in 2014.

Michigan Tech has provided a great academic home base for me, including library and archive support and computer infrastructure, as well as hope for preservation of this site.  Universities have a big obligation to their local communities, as this is especially true in this case, where the location of the university makes such a strong contribution to its quality and character.

People of the Keweenaw are inspirational---these are some of the most supportive: Gina Nicolas, Charlie Eshbach, Dana Richter, Amanda Weis, Tim Scarlett, Pat and Susan Martin, Terry Kinzel, Sue Ellen Kingsley, Craig and Jeannie Kurtz, Evan McDonald, Pat Toczydlowski.
