By Corey Lablans Photography

(19^th Week, Year 3 – 861 days – 1 missed) 

2015 10 05 – Two students in Soils, Environment and Society pour a soil slurry into a graduated cylinder. As time passes particles fall out of suspension reducing viscosity, this was measured during different intervals over a day.

(Nikon D7000 w 50 f1.8 @50mm f4 1/125^th I.S.O. 2000) 

2015 10 06 – Sometimes referred to as false grapes, Boston Ivy (Parthenocissus tricuspidata) covers the sides of many building walls at Queen’s University.

(Nikon D7000 w 50 f1.8 @50mm f4 1/160^th I.S.O. 400) 

2015 10 07 – Members of the Gem and Mineral Club of Scarborough examine various mineral specimens up for silent auction. After the break I presented on mineral/fossil collecting in Ontario.

2015 10 08 – A red maple leaf (Acer rubrum) rests amongst the grass at Break Water Park along the shores of Lake Ontario. It is recognized as the most common tree in North America (U.S. Forest Services).

2015 10 10 – Portions of a maple tree, along Westbrook Road north of highway 2, are shades of bright orange and red, as fall colours set in. The red, yellows and orange colours come from pigmentation in carotenoids, usually masked by chlorophyll.

2015 10 11 – Johnathan stands in a pseudo-carbonatite vein (calcite) that has dissolved over thousands of years and then in filled with soil. These veins are excellent for mineral collecting, as well preserved crystals can be found in the soils.
