FORT GILBERT-This was a little known fur trading post established
in 1871 at or near the site of the long abandoned Fort Henry or 1822-1823
just aboove the mouth of the Yellowstone River. To avoid militaryu
control, founders Alvin and James Leighton, and Walter B. Jordan, purposely
built it just out of the military reach of Ft. Buford, although they namred
it for Col. Charles C. Gilbert of that post. It proved to be of little
merit, and no mention of the fort is found after September 1874.
FORT HENRY-This was an early trading post established the by
the Rocky Mountain Fur Company of St. Louis, Mo in 1822. It was located
in Sec. 27-152-104, Yellowstone Twp., on the south bank of the Yellowstone
River, just above its confluence with the Missouri River. William
H. Ashley (1778-1838), later a congressman from Missouri, was the money
behind this venture, but active management was the responsibility of its
namesake, Andrew Henry (1775-1833), a native of PA. The venture was
unsuccessful, and it was abandoned in 1823.
