Mazinaw Lake in the context of "Petroglyphs"

Bon Echo Provincial Park is a provincial park in southeastern Ontario, Canada, which is owned and operated by Ontario Parks. It is located approximately 6 kilometres (3.7 mi) north of Cloyne. The park is within township boundaries of both North Frontenac and Addington Highlands, roughly separated by Highway 41. The park gets approximately 180,000 visitors annually and is a popular tourist attraction among Canadians.

Bon Echo features several lakes, including Bon Echo Lake; Joeperry Lake, along Rainey Creek; and part of Mazinaw Lake, the seventh-deepest lake in Ontario. The southeastern shore of Mazinaw Lake features the massive 100-metre-high (330 ft) Mazinaw Rock, an escarpment rising out of the water, adorned with many native pictographs.

Mazinaw Rock is a 100-metre (330 ft) high cliff in the Addington Highlands, just 30 kilometres (18.6 mi) north of Kaladar, with the closest settlement being Cloyne in south-central Ontario, Canada. It stretches for 1.5 kilometres (0.9 mi) along Mazinaw Lake, and is a landmark in the Bon Echo Provincial Park that draws the attention of many campers and cottagers all over Canada. The lake's depth reaches 145 metres (476 ft), making it the third deepest lake in Ontario besides the Great Lakes. The rock is composed of granite and black dykes. The quality of the rock varies from good on the more popular routes to bad on the less used routes.

The rock is credited in giving the name to Bon Echo Provincial Park, because it is responsible for the large echo that is unmistakable during thunderstorms and fireworks displays. Bon Echo is French for "good echo". The face of the rock is adorned with over 260 Indigenous pictographs. This gives it the largest collection of visible pictographs in Canada. Painted in red ochre on rock, they seem to depict animals—possibly creatures from Anishinābe mythology. These works may have been made by shamans, whose healing and prophetic powers are often represented in this way. Equally, they may also have served as warnings of territoriality. The pictographs are among the earliest surviving artworks in the Ottawa region.
