The temperture in the ice cave never gets above 31degrees. As rain water and snow melt seep into this cave the ice floor thickens. The ice is approximately 20 feet thick and dates back 3400 years. It has a green tint caused by an Arctic algae. In the early days the ancient Indians and early settlers mined the ice. In 1946 ice removal was stopped and at that time the ice was nearly 12 ft. high. The steps going down and then up were brutal.
The trees growning in the lava find it hard to establish deep roots. The results are that the trees grow to be twisted and gnarled. Gene did not have any problems with the hiking.
