PLEASE USE STEALTH WHEN SEARCHING FOR THE FINAL AND REPLACE IT EXACTLY AS FOUND.
We don't have enough Multi caches around here, and many of the ones we have really high difficulty and/or terrain. This one is on flat ground and should be both quick and easy to find.
Stage 1
You will find a set of three signs at the posted coordinates. Everything you need to solve for the final is on them.
Final Coordinates: N 46 20.0AB W 111 31.7CD
A = The second digit in the day that Lewis "passed a remarkable bluff of a crimson coloured earth"
B = The number of letters in the alliterative name of one mountain range that neighbors Townsend (ignore the space)
C = The third digit in the year the first train arrived in Townsend minus two
D = The sum of the middle two digits of the length of the Missouri river in miles
Stage 2
The cache. Again, make sure no one sees you searching for it. This area is usually empty when I pass by, but there are times of year and/or day that there are muggles around.
The mosquitoes can get really bad in the summer.
Congrats to TheRoamingArmadillo for getting the FTF!
