Oregon Caves - The Pioneer Exploration and the New Discoveries [first edition]

In the period of 1874 to 1894, an extraordinary thing happened in a remote part of a pioneer state in the far western United States. A series of pioneers made their way repeatedly into a rugged mountain wilderness with the sole purpose of exploring a cave. This cave is often tight, and the passages constantly twist and turn, climb up and down, and it is a chilly 42 degrees, with breezes that chill the wet caver even further. For these early explorers, without any real equipment of any kind, using slick leather-soled shoes and just a candle or kerosene lamp in one hand for light, this was an undertaking of heroic proportions.
