The Genesee River ends in my hometown of Rochester, New York completing a 160-mile journey from Potter County, PA. During its course, the river falls some 2250’. Several notable waterfalls mark its journey north.
If you read my blog, you might know that I have become an arenophile, or more simply, a sand collector. In that endeavor, I have started to collect sand along the path of the Genesee River as it crosses across mostly rural farmlands and suburban communities. Rochester is the only major city graced by its presence. The surficial geology is mostly glacial deposits (moraines, outwash, etc.) of highly variable composition, but the river also cuts into Paleozoic sedimentary rock below that is Pennsylvanian to Ordovician in age, a rock record of about 140 million years. The major waterfalls mark resistant limestone and dolostone units; intervening shale units less resistant to erosion generate gentler topography.

I wrote this article for the Spring 2020 issue of Philagems, the newsletter of an International Group of stamp collectors with an interest in “Gems. Minerals, and Jewelry on Stamps.”
I have a confession to make. I have become an arenophile. Fortunately, in many places it is not illegal (unless trespassing while doing it), and it should not be harmful to my health. I would say it is generally not contagious, but I did catch it a year ago when introduced to the hobby at a local rock club meeting. I did not realize I was hooked until the summer of 2019. While collecting minerals on trips in Maine and Michigan, I kept my eyes open for sands to collect and proceeded to fill quart freezer bags at a few dozen locations along lakes, rivers, and from glacial deposits. You see an arenophile is a lover of sand. The word is derived from the Latin “arena” (sand) and the Greek ”phil” (love).
But this is a philatelic newsletter, what does this have to do with stamps, and more specifically minerals on stamps? Well, sand is nothing more than a pile of mineral grains, and there are certainly many worldwide postage stamps depicting sand. The most popular thematic stamps depicting sand are, of course, beaches, like several of those depicted in the header. But there are also river sands, land sand, and wind-blown sand dunes such as those on this South-West Africa (now Namibia) stamp, also in the header. Why not collect and display sands from various beaches next to stamps showing these beaches? And why not call it arenophilately? Would this not be a reasonable offshoot of a group specializing in minerals on stamps? There are actually some very unique and beautiful minerals hidden in the sands of the world.

There are no rocks, no minerals, and unless there are buried mastodons, there are no fossils. But that does not mean that Zurich Bog is not an interesting place for a retired geologist to spend a few hours while remaining near home during this summer of social distancing. The small protected wetland preserve is just 8 miles north of Newark and 7 miles south of Sodus, almost smack in the middle of Wayne County, New York. Continue reading Zurich Bog
