Document Summary
Lecture 15: natural history of ontario (calciphilic plants & wolves) Petawawa river: connects algonquin park / algonquin dome to ottawa river thus fish, amphibians, reptiles are found in other parts not normally found. Purple-fringed orchid and the cardinal flower are calciphilic. Ginessic rocks are acidic thus do not contain much calcium. (1) petawawa river is in an area where the rocks split and moved apart (a fault line). Sometimes lime (which contains calcium) oozes from the joints in the rocks. (2) cedar lake, near the source of the river there are limestone rock. What happened was a meteor crashed at this location creating a crater (the brent crater). Bulblet ferns are calciphilic ferns found at the brent crater. Barron canon: there are also calciphilic plants at the barron canon. It has a little winding river around it barron river. The pile of rocks at the bottom of a hill is called a talus.
