A neat feature at a park

This afternoon Sher and our son and I went on a ‘hunt’ for a Geocache at a nearby park. We had looked it up last night on a map, and there it was! So off we went.

Explanation of how the swale works

This Geocache was not one of those hidden boxes or log books. This one was a feature at the park. We went in search of a Water Quality Bio-Swale. Yes, a feature that is designed to collect pollutants from rain fall runoff.

That’s the swale in the background

It actually looked like an ordinary swale for rain runoff. This one had a more complex design than you normally expect. There was a thick layer of sandy soil in the low part of the swale which filtered any pollutants. A layer of gravel at the bottom surrounded aΒ  perforated drain pipe in which the storm water runs off to a nearby river.

The story of Indiana’s state tree

The swale banks were planted with trees native to Indiana. One of the park volunteers was mapping the location and species of each tree while we were on site. He informed us that there will be individual ID signs on each tree and a brochure with detailed info coming soon.

      • a friend near me asked me about mozzies via fb last night – in my experience, in then’van with open doors at night, Lemongrass Oil (few drops on clothing and a few on tissue in an open jar set up on window sill) seem to do the trick here- but I don’t know whether the species at your end did get the memo. πŸ˜‰ Better luck next time in any case.
