61 (Fig. 24a) "A prospect pit on the Stacey reed Lease sunk in search of the Fort Duchesne vein, hidden beneath the mantle of boulders and river gravel from the Uinta River. The man inspecting the pit is Harry Pearson, one of the stockholders of the Western Gilsonite and Elaterite Company."1949uum_map
62 (Fig. 24b) "Wayne Thomas, mining engineer in charge, and a party of visitors inspecting preparations for pouring the concrete for the retaining wall to hold out surface water and sand until a reinforced [sic] concrete collar could be constructed on the bed-rock [sic] about 15 feet below the surface. Note several sacks of gilsonite salvaged from the vein in order to make room for the shaft collar."1940uum_map
63 (Fig. 25a) "West view of Arrowchis Shaft  showing head frame, loading platform (walled in on windward sides), simple built-in screening plant a rack of sacked gilsonite, and two stockholders, R. L. Hedrick (left), and Harry Pearson.  The upper deck served as a protective shed for the loading platform and as a floor to hold each digger's sacks, as they were hoisted from the stopes, until they were sorted, graded, and screened, after which they were racked on the loading platform below for shipment."1940uum_map
64 (Fig. 25b) "North view of Arrowchis Shaft of the Western Gilsonite and Elaterite Company, showing four-pole construction of simple head frame.  Note mine timber and bath-house (to left and beyond shed).  Clothes-line and small building to right of shed are just west of Superintendent's house hidden by the head frame and loading shed."1940uum_map
65 (Fig. 26a) "View from edge of River Terrace looking southeast along the strike fo the Fort Duchesne Vein toward the Arrowchis Lease from near the point of original discovery of this vein, just northwest of the commercial portion of the vein. Over the top of the house in the center can be seen the dim outline of a string of headframes (including those in "B" below) over the closely-spaced shafts of the Raven Mining Company."1940uum_map
66 (Fig. 26b) "Headframes over tow chief shafts on the Raven Mining Company's portion of the Fort Duchesne vein. These shafts were deepened and somewhat modernized to service the lower levels. The shafts between, and on either side were then abandoned. Note hand screening equipment, power line, and slabs for lagging the ming."1940uum_map
67 (Fig. 28) "Two views of the head-frame of the Stacey Reed shaft, taken from near the south boundary of the Arrowchis Lease of the Western Gilsonite and Elaterite Company, and from a point approximately where it is proposed to sink the new two-compartment deep shaft for pemanent commercial production. The Stacey Reed shaft here shown will serve as auxiliary manway and airway for the new shaft of the Western Gilsonite and Elaterite Company by permitting this use of their shaft, and will bear their share of the hoisting and drifting necessary to make the connection. As explained in the text, the overhead thus saved will be of vital importance to all concerned. Note the rick of sacked gilsonite near the shaft. The discovery of commercial gilsonite at this point on the vein beyond the boundary line of the Arrowchis Lease proved beyond question the ‘ore' body throughout the full length of the lease."1940uum_map

69 (Fig. 29a) "Winter scene looking southwestward from a point approximately where it is proposed to sink the new two-compartment shaft of the Western Gilsonite and Elaterite Company. The fence running west from the clump of buffalo-berry bushes in the center of the photograph is the southern boundary of the Arrowchis Lease, and the point where this fence line leaves the picture at the extreme right is where the connection will be made with the power line of the Uinta Power and Light Company."1940uum_map
70 (Fig. 29b) "Looking northwest along the strike of the Fort Duchesne vein from the Stacey Reed shaft. Almost the entire Arrowchis Lease can be seen on this picture. The fence posts in the foreground mark the southern boundary. The brush line beyond the Arrowchis shaft is where the vein passes beyond its northwest boundary. The men are ‘warming up' the gasoline hoist for the Stacey Reed shaft. Obviously, they need a hoist house."1940uum_map
