Petroleum was refined onsite to differing levels depending on what its purpose was. Differing petroleums were stored in wells like these for ease of access.

A steam engine at the Steamtown National Historic Site. Steam engines demonstrated one of the first comprehensive intersections of energy, mineral, and water resources. Steam engines required coal for fuel to boil water to make steam, as well as iron and steel for the casings and sand for traction on the rails.

Railroad tracks at Steamtown National Historic Site. Originally, rails were made of iron, but as steel production became more efficient, steel replaced it and is still used today.

Petroleum first saw widespread use in the transporation industry as a lubricant. It was refined into various products depending on which part of the engine they were meant to lubricate. It was transported in tanker cars like this one.

Steam engines used high-grade silica sand for traction on the rails. Sand was stored in a dome on top of the engine and, as the train traveled the tracks, the sand would be sprinkled down pipes to land on the tracks in front of the wheels. This would aid the wheels in gripping the tracks, especially when the rails were wet.

Fall colors can be seen in Upstate New York along the banks of the Tioughnioga River near Whitney Point.

A Whooping crane chick is released into a temporary pen to acclimate before being released into the wild.  Four of the endangered chicks, hatched and raised by their parents at the U.S. Geological Survey’s Patuxent Wildlife Research Center in Laurel, Maryland, were released on Necedah National Wildlife Refuge in Wisconsin.
