I thought these ripples on Rauchtown Run would make for a nice image. They were captured at Ravensburg State Park while we walked a bit before sitting down to a picnic lunch under a canopy of Hemlock and Beech trees. The water was down and this caused standing waves to form wherever the stream bed moved close to the surface. Water fascinates me and I’ve always been curious to know how many water molecules comprise any particular volume. Writing this post drove me to the calculator to discover that there are more than 10,000,000,000,000,000,000,000,000 molecules of water per liter and approximately 10,000 drops in each liter which means there are 1,000,000,000,000,000,000,000 molecules of water in every drop. What’s more impressive is the list of water’s physical characteristics which make life, here on earth (and elsewhere perhaps) possible, but that is a topic for another day. Water is a nonrenewable resource and life depends on it … treat it well, it’s all we’ve got.
