Field trips - the KeweenawWeek has numerous field trips to the rock piles of many mines. One of theeasiest - and most legal ways to gain access to the sites. The rock piles arebulldozed to expose new portions of the dumps. Photos from KeweenawWeek 2002, Keweenaw Week 2003 and Keweenaw Week 2004.

Be sure to check with the local residents for the status of various minewaste rock dumps and the persons to contact for permission to collect.

The Seaman Museum - a MUST SEE, they have one of the largest displays of minerals in the country with anexcellent representation of minerals from the area. Plan a minimum of two hours (fora single quick pass through the collection) forthe visit.

Other museums in theNational Historic district or area.

     Coppertown USA - Copper Mining Museum in the Keweenaw Peninsula, UpperMichigan
     CopperRange Historical Museum
     Houghton County Historical Museum - Lake Linden
     Quincy Shaft Historical Association

Underground Mine tours
     Quincy
     Delaware
     Caledonia - primarily during Keweenaw Week(historical & collecting tours)
     Adventure - closed for 2004 - due to reopen for 2005.

Use of a metal detector-  It will be of use in finding buried pieces of copper and/or silver (especially on newly worked "poor rock" piles and the bulldozed piles during Keweenaw Week). The green/blueoxidation products do make the copper easily visible when on the surface after the mud and dust have been washed off by rain(against the red/brown of the country rock). Some of the rock shops have thesefor rent (approximately 2/3 of the participants of the Keweenaw Week field tripsuse detectors).

It is extremelypleasurable to work with knowledgeable curators. I would also like to thank DanBehnke for permission to use his photographs of some small, but exquisite,mineral specimens from the Keweenaw. I would also like to thankStan Dyl and the staff at the Seaman Mineral Museum.

Winter is not the season to collect in the Keweenaw. Snow has compacted toabout two feet in depth (March). Gauge shows the amount of snow that falls in the area (height of gauge is 32 feet).


Great Sand Bay in winter. The ice forms ridges parallel to the shore where ithas been pushed onshore by storms in Lake Superior. Ice erosion and storms inthe fall and winter helpreplenish the beaches with semiprecious stones.

 

Scenery
Report of B. Hubbard 1840 - to Douglass Houghton

     The stern rules of science may seem to compel the geologist to take littlenote of the merely picturesque features of the landscape, yet, called as he isto view them in their wildest character he cannot be altogether insensible tothe grandeur and majesty, or the variety and bloom of nature. The sublimemountainous scenery of the eastern states has been often and justly dwelt uponwith admiration, by both the geologist and the traveler. Little of the peninsulascenery partakes of the grandeur of primitive and more broken districts, butnone can fail to notice one superior charm, which more than compensates, in theeyes of those who are content to overlook the romantic aspect of the land, forthe consideration of its solid bounties. To the cultivator of the soil every consideration which its picturesque character presents will yield before the morepractical one of its fertility.

     But few could have traversed the varied portions of our state, over which myduties during the past season have led me, and compare their rich scenery will,that of more eastern lands, with any feeling of disappointment. The ordinarycharacter of the "openings" is that of a majestic orchard of statelyoaks, which is frequently varied by small prairies, grassy lawns and clearlakes. These magnificent groves were, until within a few years, kept freefrom underbrush by the passage through them of annual fires, allowingsuccessive growths of herbage to spring up luxuriantly, covering the surfacewith a profusion of wild flowers and verdure.

     The variety so essential in a landscape of woodland, glade and sheets ofwater, are here combined in a manner which seems the result of art, but which isnot less truly inimitable It is difficult to resist the impression that we aresurveying an old abode of civilization anal of tasteful husbandry. It resemblesthose exquisite pictures of park scenery, where the vision roams at will amongthe clumps of lofty oaks and over open glades, gemmed with flowers; while thedistant woodland bounds the horizon, and the velvet-skirted lake gleams upon theeye as it reflects to light from the open prairie, or is faintly visible fromthe bosom of the glen, reposing in silent loneliness.

     Such scenes, it is true, are destitute of the rough majesty of mountainaspects, but they have that all pervading, tranquil beauty which forsakes thelofty hill side and the hoary cliff. They present nature in her simpleloveliness, without any stern aspect and her masculine attire. She has bestowedher blessing upon the land, and spread over it her robes of beauty.

     The limits of an annual report, prevent more than this very meagre notice ofsome of the characteristics of our peninsula scenery.
