As COVID-19 evolves, it’s important for you to consider the risks and manage them appropriately. Remember to read all signage before entering any trail system.
When choosing to find PtboCountyCaches geocaches, we encourage you to:
- Stay home if you’re feeling sick
- Maintain 2m physical distancing with people outside of your social circle
- Carry hand sanitizer and use it before AND after contact with geocaches
Please note: cache containers are not officially sanitized at any time. If you do choose to open a cache, it is at your own risk.
This cache has been placed as part of an initiative by the County of Peterborough, its member municipalities, the City of Peterborough and local First Nation communities to celebrate Canada 150+. There are 23 geocaches placed throughout the region showcasing local history.
If you would like to participate in this initiative you can download a Travel Diary at (Geocaching at Peterborough & the Kawarthas Tourism). Find at least one geocache in each of the Townships, First Nations and in the City and stamp your Travel Diary. Once you have completed the Travel Diary, you can visit the Peterborough and the Kawartha’s Tourism office to pick up a limited geocoin. New coins in stock in 2018.
On the lid of the cache container you will see a stamp. If you have a stamp pad with you, great, use that to ink the stamp and stamp your Travel Diary. If not, use the crayon or the pencil in the cache container to "rub" the impression of the stamp on your Travel Diary.
This lime kiln was built in the 1880’s on the farm of the Sedgwick brothers, Robert, Ralph and William, and used until the late 1920’s when it became unprofitable. The main purpose for this lime kiln was to provide slaked lime for hide tanning in Hastings. Other uses would have included building mortar, plaster, floor construction, and agricultural land treatment. An example of slaked lime can be seen at the Sam Edgar Crypt cache in this series.
The kiln was loaded from the top, alternatively with limestone from neighbouring farms and cedar logs from nearby swamps. Once filled, a fire was typically started at the bottom on a Sunday at midnight. The limestone was heated to a consistent 1,000°F for 3-4 days to drive out the carbon dioxide and leave calcium oxide (quicklime). After cooling for a couple of days, the unstable ‘cooked’ quicklime stones were removed from the bottom opening by shovel, put in boxes, and run with water to slacken them.
The Sedgwick - Webster Road Lime Kiln is one of the few remaining intact kiln’s left in Ontario. Due to the historical importance of the kiln, the Township of Douro-Dummer purchased the 70ft. x 175ft. section of land with the intent to fully restore the kiln on this township park.
