Back at Jokers Hill …


March 7, 2013. Things have changed at Jokers Hill while I was in the south. My last day here at the very end of January it looked like spring was around the corner. The fields behind the research barn were completely free of snow as you can see from this photograph.



The sun was bright that day and gave me the opportunity to shoot a self-portrait, my shadow stretching across the grass.

me and my computer bag, not a bustle worn in front 
Though it was chilly and windy the sky was patched blue and white and I remember it felt good to walk, and easy, the ground hard underfoot and clear of snow. But snow fell in February, quite a hit of it in fact, and I’ve come back to lots of white on the ground and a white winter light today. But it’s not cold, the skiff of snow that accumulated on the car overnight has melted and what’s underfoot feels punky.

I came up briefly last weekend for a walk around with my family, and to check out what I needed by way of food. Saturday afternoon the wind was brisk, and we huddled into our jackets. That bare field had fallen back into its winter self.


Snow was heaped like boulders where the road had been ploughed. It must have been quite crusty and hard, perhaps there'd been some rain or at least shifts in temperature as well.



In spite of the snow and cold, things are stirring at Jokers Hill. Even on that cold Saturday afternoon walk, signs of a change were present in the increased colour of the willows. And we saw a Pileated woodpecker!


John’s hibiscus are flourishing. They made us warm just to look at-- but it was also nice to spend a few minutes in that greenhouse-feeling room. 



Yesterday afternoon I went to the Naturalists' Training Course session on fungi and lichens, and while we were outside scraping lichens off fences and trees to look at under the microscope, two Pileated woodpeckers flew over. We heard them call, and then, more impressively, their incredibly loud hammering on trees. It sounds like a huge drum. More on the fascinations of lichen in another post.

On the beach


I’m a long way from Jokers Hill at the moment, staring out at the Gulf of Mexico from a condo in Indian Shores, Florida. The morning has opened with cloud but it’s warm, people are walking in shorts. The waves wash in over and over again and their sound cancels the traffic from Gulf Boulevard, except for the occasional heavy truck. 

I walked on the beach a little while ago myself, filling my sandals with sand that’s surprisingly soft, and found myself wondering just what rocks have been ground down to form it. I wish I knew more geography and geology. 

As I walked I took photographs, picked up a shell here and there, watched the Ruddy turnstones busy at the waterline or feeding on the remnants of a shelled creature. 



KSR hosts a Naturalists Training Course and at the end of January I joined it for the class on geology.  (If you're curious about it check out this link: https://ksr.utoronto.ca/naturalistCourse)

Among the things I learned was that the Canadian Shield—a feature I’ve known about for as long as I can remember, and one that seems to be part of the Canadian identity, at least for my generation—is part of a much larger formation called the North American Craton that is the core of North America. If I understand it correctly, it also links up to Greenland and the Hebrides in some way—so that it’s actually reasonable for the Appalachian Trail folks to be working on extensions of the International Trail in Europe. (More about that, perhaps, another time.)

Here’s a link to an image of the Craton with information about it: http://www.mnh.si.edu/earth/text/4_1_3_1.html

As you can see, Florida does not rest on the Craton. I’ve discovered it’s a large plateau formed by a combination of volcanic activity and marine sedimentation, but I don’t have that formation clear in mind yet, and since my knowledge of geology is so vague I can’t say what the sands here have come from. Clearly I need to work on geological literacy. 

But even without that it’s fascinating to walk the beaches and look at what the sea has tossed ashore.

Then there are the grotesque finds:


I think this is some sort of sponge, but I don't know that for sure ...
