Hartington, Ontario

Harrowsmith is a community in South Frontenac, Ontario, Canada. Located north of Kingston, it was once noted for the cheddar cheese produced by the Harrowsmith Cheese Factory. As a farming village in an area resettled by many back-to-the-land emigrants from urban areas in the 1960s–1980s, the village gave its name to the country living magazine Harrowsmith. The village was once the junction of the Bay of Quinte Railway and the Kingston and Pembroke Railway. These rail lines eventually came under Canadian National Railway (CN) and Canadian Pacific Railway (CP) ownership respectively. The Harrowsmith railway station had a livestock pen, facilitating the transportation of livestock by rail. Both lines saw eventual abandonment and conversion into rail trails known as the Cataraqui Trail and the K&P Rail Trail, which still meet each other at Harrowsmith as their railway predecessors did.Harrowsmith is home to Centennial Park, a large park adjacent to Road 38 which includes soccer fields, baseball diamonds, play structures and hosts many community activities.

The Holleford Crater is a meteorite crater near the community of Holleford, part of South Frontenac, Ontario, Canada. It is 2.35 kilometres (1.5 mi) in diameter and the age is estimated to be 550 ± 100 million years (Ediacaran or Cambrian). Although there is a surface depression over the area, the crater itself is not exposed at the surface. Holleford Crater was discovered in the 1950s during analysis of aerial photographs under the direction of Carlyle S. Beals of the Dominion Observatory in Ottawa. In the late 1950s, the Geological Survey of Canada conducted a series of four geophysical studies: magnetic observations, seismic studies, gravity studies, and a diamond drilling program. The seismic and gravity studies and the drilling all produced data consistent with the impact theory. The drill core revealed breccia and similar materials at predicted depths. The studies concluded that an ancient meteorite impact crater is present in the Precambrian bedrock below the surface. The meteorite was estimated to be approximately 100 metres (330 ft) in diameter and to have impacted at approximately 55,000 kilometres per hour (34,000 mph).
