The slide show is an expansion of a project outlined in Wilson (1994), and is an on-line example of the "tutorial" content envisaged for the CD-ROM version of the MINLIB database. The images were mostly chosen from a show presented at the Bancroft Gem & Mineral Club, 10 October 2001. The first on-line version was installed on 27 October 2001. Twenty such tutorials are envisaged for the first edition: one or perhaps two examples will appear on this web site.
There are three levels of captions of progressively higher detail and complexity. The audience levels are not precisely defined, but might be described as; "junior school", "curious adult" and "specialist". Click below to take the Tour!

and, best of all, for geological insights into the region:
The Institute on Lake Superior Geology
Selected References on the Lake Superior Region
The following references have been selected largely from the viewpoint of the rockhound, but there is some excellent general reading here on the region, and much to interest the professional geologist. Serious students of geology, mining, hydrology and related disciplines can learn much from the Institute on Lake Superior Geology, a unique annual meeting with a strong focus on field trips. Five of the photographs displayed here were taken on ILSG trips between 1993 and 2000, and several others were snapped en route to and from these low-key but highly professional events.
N.B. The reference list has been slightly updated, but much more could be said!
