Here we are at Traveler's Rest in Lolo MT. which is now a brand new state park.  
The Corps stayed here in September, 1805 just before the crossing through the
Bitterroots over Lolo Pass into Idaho.

In the distance is Lolo Creek which flows into the Bitterroot River, about 300 
yards to the right.  The field shown in this view is where the latrine probably 
was, and where traces of mercury from Dr. Rush's "Thunderbolts" were found 
just recently.  Dr. Benjamin Rush was the foremost doctor of medicine in the 
United States at the time and recommended his strong purgative pills as a 
sovereign remedy for most ailments.

In the following picture we see an archeological crew working on the site where 
the actual campsite is supposed to have been located, about 100 yards (100 m)
to the left of the picture above.
