Leroux Island is not mentioned
in Sitgreaves' published journal but the above plate appears in the
report. It is also noted on the large map that was published with the
report. The "island" today is just a hill in the middle of
the usually dry river bed. The foreground rock in both pictures is
on a low hill on the river's north bank, probably at the expedition's
Camp 4.
I'd like to comment on a couple
of interesting things about these pictures. First,
the men in the top picture are too small in scale compared
to the actual size of the rock they're standing on.
Second, note left side outline of the rock the men are standing on.
The rock in
the photograph has the same contour as the bush in the lithograph
above. The explanation is that the lithographs
were done later in Washington from rough field sketches and the
lithographer had to fill in details that weren't clear in the drawings.
