Orion never mentions Carson Sink Station, Tuesday, Aug 13.—"Arrived at Carson Sink where Carson river loses itself. It is a beautiful lake, 25 miles long by 15 wide, and 60 miles from Carson City." This tells me they passed north of Carson Lake, whereas Burton: "Round the S side of the lake to the sink of Carson River Station, no provisions; pasture good; fuel scarce 23. Cross a long plain. Ascend a very steep divide and sight Sierra 50 miles distant Descend to Carson River Fort Churchill newly built Sutler's stores, etc." Carson Sink, as a geographic feature is much larger than either men has described, although Burton seems aware of its nature as an endorheic basin. The locations of stations I've mapped for my project have come primarily from a study conducted for the National Park Service. They distinguish between Ragtown and the Carson Sink Station. A page with my mapped locations is at http://twainsgeography.com/node/682 The map can be enlarged and all the station locations are links.
