The Ubiquitous Mason Jar


lots of duckweed, little bit of water

We went to the river park this week. There are steps down to the Big Thompson river, where you can float or splash, or put in your tubes and drift down the river. We didn’t bring tubes, but ran into friends who shared with Kate.  There are sprayers where the little kids can shriek and splash and get soaked in relative safety, and there is a bridge under which the water slows down a little, spreads out into shallows, where you can look for crawdads. This is where we spent the bulk of our time. The boy discovered that when crawdads are really little, they just tickle when they pinch.

In Gaia’a Garden (I know, terrible title, great book) there is a description of a project where you take water samples from several different places, with plants and muck and life, mix them in a mason jar, put the lid on and then watch. The idea is that you are mixing elements and creating an ecosystem that is not quite pond, not quite river, not quite lake, but a blend of the three.
I told the boy about the mason jar project at bedtime, and he was fired up- he couldn’t think about anything else. Right after breakfast he asked for a jar, and kept asking when we could go. Obviously, I needed coffee first. And there was that pesky dental appointment…

We went out in the afternoon, after a wonderful thunderstorm. There is a wetland by Kate’s school, but no way to get to open water, so we wound up going to the Sculpture park near our house. This park has a chain of wetlands, culverts and open water, so we were able to find swampy still water, fast running aerated water, and duckweed covered water.

This lake is usually deeper than this…

The final piece of the puzzle was mud, from the reservoir. They have been lowering the water level alarmingly, and we had to walk out quite a ways in the mud. It was pretty gross.

The water is clearing, and the mud has settled, and we can see stuff swimming around.  The boy had high hopes for a minnow, but I don’t think we caught one.

Yes, I am aware of what 3 cups of pond water would smell like if it spilled on top of legos. We would probably have to move. But, we are also trying not to spill.
