24 JULY 2010 Caution Note added: The current NGS DS, and of course this page, still carry the bad L/L.
Should say "seen it". Great to have lots of experience on the search.
Edited 3 Jan 2010 prior to entering in the "chiseled marks" forum.
Describe in the 1912 COE Bulletin No. 3, 'Bench Marks on the Missouri River' P 110
'Gauge B. M. Madison-Jefferson River: Is on R.B. 0f the Madison-Jefferson River, about 1/4 mile above mouth of Gallatin River, 30 feet above and 20 feet back of gauge, 30 feet up-stream from a path leading from skiff landing up cliff of rock; being cross cut on top of rock cliff, marked thus (shows a B. M. over an X) Elev., 3627.793.'
A note on page four of this reports indicates that 413.77 feet needs to be added to bring it up to the mean Gulf datum, or 4041.563. The DS posted benchmark elevation is now 4046.05
