Location: On the Safe Harbor Dam fishing platform, find the high water level markers on the dam wall. 39°55’29.4″N 76°23’21.6″W.

History Brief: At full load, 30 million gallons of water per minute pass through the turbines at Safe Harbor. With its record-setting rainfall for Pennsylvania in 24 hours, Hurricane Agnes changed that to 931,000 cubic feet per second, about five times the flow over Niagara Falls.

Clue: Record the height of the Susquehanna River at Safe Harbor on June 24, 1972.

2. Lock 

Location: Just north of the River Road bridge that crosses the Conestoga River in Conestoga River Park. 39°56’23.0″N 76°23’12.8″W.

History Brief: During the 1800s, the Conestoga Navigation Company attempted the bold venture of turning Lancaster into a port city via the Conestoga and Susquehanna Rivers. This plan involved building a slackwater canal that ran a winding 18-mile course through a series of locks and several dams between Lancaster and Safe Harbor. Lock 8 is still visible today.

Clue: Standing at the northern end of the lock ruins, count the number of stones stacked in the first column on the left while looking downstream. Record the number. (one-digit number)

3. Rolling Mill

Location: The tennis courts at Safe Harbor Park. 39°56’01.7 “N 76°23’05.6 “W.

History Brief: Safe Harbor Iron Works was built to produce iron for the thriving Pennsylvania Railroad. The rolling mill was the largest of all the structures. It covered over an acre of ground and stood on the present Safe Harbor Park’s tennis court site. Inside the building, hot slabs of metal were passed between rollers. This action squeezed the iron to a specific thickness in the production of rails for the railroad. In the mid-1800s, Safe Harbor produced one-eighth of all rolled iron in Pennsylvania.

Clue: Find a 3D printed gray medallion with black lettering. It is attached to a tree between the road and tennis courts hanging around eye level. Record what’s printed on it. (two letters)

History Brief: Hidden in the forest near the Conestoga River lies a huge rock outcropping covered with mysterious carvings.
