Early morning hoar frost, calm winds, and a hazy sunrise got me out the door with my camera Tuesday morning.  I found plenty to photograph, including frosty milkweed seeds, mouse tracks, and lots more.  But it was the little windows in the snow that I couldn’t stay away from.

It appears to me that many of the holes in the snow were a result of radiant heat, caused by the sun warming up the plants sticking out of the snow.  Regardless of the reason, they were sure interesting to look at – especially with the morning hoar frost tinging their edges.

Here are just a few of the images I came home with.

I assume many of the holes were caused by heat radiating from vegetation warmed by the sun?

Some of the holes were more like cracks...

Frosty Morning Walk

We got our first real snow of the season last week.  Early Friday morning, I braved the icy roads and made it to our Platte River Prairies in time for a sunrise walk.  It was a beautiful morning.  The temperature was about 10 degrees Fahrenheit, but there was only a very slight breeze, so it didn’t feel cold – especially after walking through 2 foot snow drifts for a while.

I walked across snow-covered prairie to one of our restored wetlands, where a dozen or so ducks flushed off a small bit of open water.  A real duck biologist would have been able to identify them by their calls, but their silhouettes against the pink horizon didn’t give me enough to go on.

Not much else was moving around.  I didn’t even see many tracks in the snow, apart from those of a few small birds that had been feeding on fallen seeds from sunflowers and prairie cordgrass.  I walked around the wetland as the sun came up, enjoying the quiet and taking some photos of frosty wetland plants.

As I walked back to my vehicle, I thought I heard sandhill cranes calling in the distance, but I might have been imagining things.  There have been a few thousand cranes hanging around this winter, but I haven’t seen them for the last week or so.  An immature eagle flew overhead, flapping steadily as though it had somewhere to be and didn’t want to be late.  Just a few feet away, a meadowlark flushed out of the snow and flew about 30 yards to a short perch in the grass.  I bent down to see where it had come from and found a meadowlark-sized hole.  The hole led into a “den” formed by an air pocket in the snow beneath a clump of tall grass.  I took my glove off and put my hand down into the still-warm hiding place.

Eventually, I reached my parking place, shucked off my snow-crusted coveralls, and picked up my cell phone to join a conference call – only a few minutes late.  It was time to get back to work.

Here are a few more photos from the frozen wetland.
