The Niagara Glen is a geological wonderland, acres of tumbled rocks which fell from the cliffs above. Here about 8000 years ago the unbroken crest of the Falls was eroding southwards from Queenston-Lewiston and was about to be separated by a higher central limestone mass.
Possibly about 100m years later the crest was separated and fed by two channels- a higher thinner current on the present Canadian side, and the rest of the original stream on the American side. In the centre was a long thin island, now reduced to a mass of debris by erosion. A dry gorge was caused on the western/Canadian side when the faster erosion of the larger eastern stream cut off the small western stream’s flow from the rear.
The area of the river bed that was cut off and left dry is now known as Wintergreen flats, and it is on this table of land that the Niagara Glen picnic area is located. Approximately 7,000 years ago, erosion in varying depth, by two separate cataracts in sequence, produced a major falls with a 76 m (250ft.) drop over the low Whirlpool Sandstone.
From the parking area, cross the picnic area (Wintergreen Flats) and descend down the steel stairs. Follow the White trail (Cliffside Path) to the right and continue on the Green trail (Eddy Path). Close to the water take the Blue trail (River Path) to the left. Cache is a small camo Lock & Lock container and within a meter of the trail. Take care and enjoy!
