Slough Caverns & Caves - The Newly Discovered Subterranean Wonder

The history of Slough Caverns dates back to the beginning of the Quaternary Period.

The Quaternary is a subdivision of geological time (the Quaternary Period) which covers the last two million years up to the present day. (The exact duration is a matter of debate with estimates of the onset of the Quaternary Period placed at between 1.8 million years and 2.6 million years by different authors) The Quaternary and the Tertiary Periods together form the Cenozoic Era. The Quaternary can be subdivided into two epochs; the Pleistocene (two million years to ten thousand years ago) and the Holocene (ten thousand years ago to the present day).

It is believed from the preliminary evidence that much of the early formation of the Slough Cavern system took place 10,000 years ago in the early quaternary Period.
