PETROLOGIC DATA
Rock Number: 1
-Good para-amphibolite material. Thought at first could be highly stretched basalt as at Pipestone Lake but it is continuous in layering on outcrop scale (>100m)
-Layered at 0.5 to 5 cm with fine internal laminations
-Extensive boudinage of mafic layers and quartz veins
-Rare calcsilicate diopside-plagioclase layers.

Rock Number: 2
-1 m. dike of grey (buff weathering) aplitic granite parallel to layering
-possibly not dike but sand layer, but not likely
