- What's This?
Here’s something on my path toward dragonflies on the bogs and along the lakes of Saskatchewan, Canada. Name it and win $5 off any of my outings or lectures. And if the summer monsoons have driven you indoors with time to kill, consult the complete lineup in the What’s This? challenge. (Collect the whole set!)
Added July 6: Well, this one was easy. Everyone got it. What the heck have you all be doing in Michigan?
Yeah, it’s a fossilized coral that went by the name of Hexagonaria percarinata. It now resides in rock formations dating back to the Devonian about 350 million years ago (an important period in dragonfly evolution, by the way). But why so round and smooth? Easy: glaciers and waves. Glacial ice sheets plucked chunks of the fossilized reef, ground some of their rough edges, and left them to the waves of Lake Michigan, which have a way of smoothing out many things. We find these gems around Petoskey and Charlevoix, Michigan. It looks as if Patti Haynes was first to name it as fossilized coral and Kathleen Moore put its “type location” on the title. Both winners. It’s nice to see a few Michiganders in the mix of replies. Sara Backer wins her customary honorable mention (for wackiness, er, I mean creativity).
That particular stone pictured above has been with me on journeys for decades. I’m not one for ritual, but that pebble makes me feel safe (which is why it rides with me on my motorcycle). There’s power in rock. By the way, I’m in Thunder Bay on Lake Superior, and below is where I’m heading (with my canoe, camera, and insect nets), which means you won’t hear from me for a while. Damn, many miles to go — but many bogs and prairies on the way.
