Earth’s atmosphere (Jan. 14, 2017)

Why do puffy clouds have flat bottoms? This was just one of the many questions Rob posed as we explored different aspects of earth's atmosphere. Earth's breathable atmosphere is the only habitat we really, truly live in, but owing to the normal invisibility of air, we forget about it. So why are clouds flat on [...]

Skulls and bones (Dec. 10, 2016)

Macouners are notorious scavengers of skulls and bones, routinely raiding a friendly trapper's carcass pile with abandon, and dragging home items that parents with more sensitive noses may relegate to the garage, the backyard, or even earthen burial. But well chosen, cleaned, and prepared specimens can be things of fascination and beauty. OFNC member Jim [...]

Rob’s winter forest (Dec. 3, 2016)

Macoun leader Rob Lee lives in the forest, and today we explored part of it. We found a good lunch place where the bare deciduous trees (Sugar Maple, Beech, and Ironwood) let a little sunshine in, and a few White Pines provided dead, dry branches for a hot, steady fire. The temperature never got above [...]

The Story of Stuff (Nov. 12, 2016)

We began by reviewing last week's field experiments, in which we measured the speed of sound by timing three repeat echoes off an isolated house (getting a result of 1010 feet per second). Rob explained how we can use that figure to tell how far away lightning is striking as a storm approaches. We had [...]

Up the creek without a paddle (Nov. 5, 2016)

Indian River is a minor watercourse that runs slow and deep out into the farmland of Lanark County, but has its origins in springs and lakes in hilly country. We settled down for lunch in woods beside the last stretch of rushing water above miles and miles of marshy meanders. The steep valley sides seem [...]

Silicate minerals in our world (Oct. 15, 2016)

Quartz, olivine, garnet, pyroxene, hornblende, the micas and the feldspars – what unites them? There is an underlying order in their composition. They are all share chemically identical molecular silicate skeletons. It is said that if you get to know the minerals just named and recognize them when they appear in more complex rocks, you [...]
