Long abandoned historic Tie Hacker Camp in the High Uintas. Tie hackers in this area were an important part of the building of the coast to coast railroad. Tie Hackers cut railroad ties from the lodge pole and other pine and fur trees in the Utinas and hauled them to the construction sights where the railroad was being built. Both the Union Pacific and the Central Pacific used ties harvested and shaped from this area.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5500 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
Elements are fundamental substances of matter - matter that is composed of the same types of atoms. At present, 118 elements are known. Of these, 98 occur naturally on Earth (hydrogen to californium). Most of these occur in rocks & minerals, although some occur in very small, trace amounts. Only some elements occur in their native elemental state as minerals.
To find a native element in nature, it must be relatively non-reactive and there must be some concentration process. Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state as minerals.
Copper is the only metallic element that has a "reddish" color - it’s actually a metallic orange color. Most metallic elements, apart from gold & copper, are silvery-gray colored. Copper tends to form sharp-edged, irregular, twisted masses of moderately high density. It is moderately soft, but is extremely difficult to break. It has no cleavage and has a distinctive hackly fracture.
The Michigan rock shown above is a large, 1.1 ton boulder of native copper that has a greenish alteration coating of malachite. This boulder was transported by glaciers during the Pleistocene Ice Age from its original location in Portage Lake Volcanic Series bedrock (= the host rock for most of northern Michigan's copper). The original copper mineralization age is 1.05 to 1.06 billion years old (late Mesoproterozoic).
Locality: near Houghton, Keweenaw Peninsula, Michigan, USA

From 8-10 May, 2015, Waag Society and The Netherlands Institute for Sound and Vision hosted the first of six Europeana Space hackathons. This was the main objective: come up with appealing ideas and applications to bring the rich archive of digitized European cultural heritage to the public.
The Europeana Space Project seeks prove that digitized cultural heritage material can be used in creative ways, and new business and sustainability models can be developed around these innovations.

A sophisticated proof press that incorporated precision enginering to approximate actual press conditions. The Hacker company sold to Vandercook & Sons in 1937 and this model was discontinued. There is some discussion that Hacker was making a better proof press than Vandercook was but these cost more, so coupled with the Depression, Hacker had to sell out. Scanned from a print made direct from the original 8x10 Hacker negative in our collection.
