A high pressure ridge sits over this part of the country, sealing in the heat. That, plus a jacked-up climate, has resulted in weather that is like God’s own convection oven set for “broil.” Despite the record heat, the nearby Southwest Nature Preserve pulls at me like an arcade game for a little kid, and the weekend could not pass without my wanting to play it just a couple of times.
Yesterday, July 21st, I decided that surely a walk at sunset would be OK, so I walked the perimeter of the preserve from about 8:30 to 9:30pm. According to my car, the starting temperature was about 101F. I made my way down the trail to the pond at the northwest corner, where the diameter is shrinking toward hot tub size and the water temperature is just right for that. Walking down onto the spongy exposed mud, there was no sign of the leopard frogs I recently saw, but I did surprise a bullfrog that jumped into the hot tub with a splash. Above the pond, several swifts flew their typical aerobatic, twisting dance, and I hope they caught plenty of insects.
The insects were the living things most in evidence. Grasshoppers jumped and flew ahead of my steps, and cicadas droned in the background. I walked around to the yucca meadow, and searched the sand by flashlight. I’m guessing that the Comanche harvester ants had been sheltering deep in their colonies, but I did find one solitary ant, carrying a fragment of something and presumably searching for the opening down to join her sisters.
Back in the woods, I checked Weather Underground, which reported the Arlington temperature as 98F, at 9:00pm. The walk back was quiet; the woods were still and the sumacs were wilted, and no Chuck Will’s Widow graced the evening with its beautiful calls. It seemed that everything except the cicadas had retreated into shelters to wait out the heat.
This evening, in a fit of lunacy, I decided I wanted to see what the place was like in the full flowering of the broiling sun. When I arrived, about 6:40pm, Weather Underground said that Arlington was enjoying 112 degrees of late afternoon sun. I walked down to the smallest pond to see if any water remained. As it turned out, the drying of the pond has been a bonanza for the water primrose, which had an ever-widening band of muddy bank which it has covered in luxuriant growth. The center of the pond still has some water, for now.
I walked over to the biggest pond and saw a little blue heron flying off over the water. Dragonflies were active all throughout the preserve, but the big pond was Odonate Central. I stood on the bank, with no turtles to see and no cricket frogs hopping to safety, trying to zoom my iPhone in for a satisfactory photo of one of these acrobatic little predators. I suppose I felt I had to photograph something.
Walking back, I spotted a group of several northern cardinals in a group of oaks and understory plants. I got a good look at a male, and caught glimpses of others through the leaves. I did not linger to see when they would move on; it had been a tough couple of walks, and I was only good for about a half hour today, with the temperature still at 104F when I left. Life goes on at Southwest Nature Preserve, sheltering from the worst of the heat or (in the case of the dragonflies) flying in complete defiance of it. Good for them. I’m headed for shelter.
