Wow! I've gotten used to thinking of myself as a flatlander. Rock Dunder, just south of Morton off Hwy 15 is a reminder that we actually have topography. Its a great hike, (if a little challenging to the knees) up to the bluffs which line the Rideau Waterway. So nice to be on granite and quartzite after all that limestone. And so wonderful to feel the forest floor under your feet. When you get to the summit it's bare, smooth, glaciated rock with fantastic views along the river and beyond. Apparently the formation, part of the Frontenac Arch biosphere, is a pluton. A pluton is an old volcanic plug, from which the exterior has eroded away leaving the hard igneous core. Gros Cap, near the Sault, is a similar formation but its called a batholith. I'm sure all those vulcanologists out there could tell me the difference. I'll google it later. Whatever it is, it is beautiful. The smooth rounded curves of rock, the fresh breeze, being up there with the turkey vultures wind surfing. Great!
In the forest there was a profusion of wild flowers in blossom. Hepatica, saxifrage, violets; yellow, blue and white, Canada mayflower, blueberries, uvularia, dutchman's breeches, and of course, the trilliums; white and red. Needless to say, many pictures were taken.
It was hard work going down the steep descents over roots and rocks, but a great workout!
