This cache is part of the Oregon History
Lesson series!
A multi-waypoint cache that is part of the Oregon History Lesson Series started by fractal. This cache starts at the above coordinates, which is the location of the historic Willamette Falls Locks. Built in the early 1870's by the Peoples Transportation Company to help move river traffic around the falls, the locks helped transform the development of Oregon's pioneer society and improved river transportation in the Willamette Valley. The falls were also an early site of an Indian fishing village. Water flowing over the falls furnished the power for a lumber mill which began operation in 1842, a flour mill in 1844, a woolen mill in 1864, and the first paper mill in the Pacific Northwest in 1867. The first long distance electric power transmission in the United States was from the falls in 1889. Begin your adventure by parking at the following coordinates:

From here walk down to the coordinates of the locks. At the coordinates for the locks you will need to find the following information to determine the actual cache location:
1.The year the locks were opened. (A)______________
2.The year the Spruce Goose went through the locks. (B)_____________
3.The year the lock doors were renovated. (C)_____________
4.The year the locks were designated an OREGON HISTORIC CIVIL ENGINEERING LANDMARK. (D)_____________
Be sure to use the correct date for the designation. Do not use the National Historic Landmark date.
TO COMPUTE THE GEOCACHE LATITUDE: 45° WW.XXX
Subtract 1,852 from (A)____________.This represents LAT WW
Subtract 1,739 from (B)____________.This represents LAT XXX
TO COMPUTE THE GEOCACHE LONGITUDE: 122° YY.ZZZ
Subtract 1,905 from (C)____________.This represents LONG YY

Visitor access to the locks is limited to daylight hours. Children should be supervised and pets should be on a leash as this area is part of a working warehouse and paper mill.
Please note: when you arrive at the cache location, a short five minute drive from the locks, it is on the east side of the walkway. Don't look over by the nearby houses. It is close to the walkway. You will need to do a little poking around to find it, but you don't have to move anything. It is a small tupperware container so bring small items to trade.
PLEASE BE DISCREET ABOUT LOCATING AND REPLACING THE CACHE.
