Located in Deersdale District, New Brunswick, in a valley that was severely burned by a large forest fire in 1982, the Otter Brook site has several interesting features. The most important of these is a narrow but deep canyon, eroded in a layer of brittle bedrock by the rushing water. River canyons in this region are rare, but are usually the result of fault activity, where two portions of the earth’s crust pull away from each other. The Otter Brook canyon may be the only example of its kind in New Brunswick that was created by water erosion. At the mouth of this canyon are the remains of an old dam at the bottom of the stream. Below this dam, on the southern bank of the stream, is a cavern, carved out by the rushing water. The cavern is 4 or 5 meters deep and has several round pillars left behind by the brook’s erosion action at its entrance. As a result of a severe fire in the valley the poorly regenerated site allows for a clear view of a number of glacial deposits in the form of drumlins and moraines scattered on the landscape.
