Frank A. Welder: Get facts straight about lava flows

To the editor:

According to your article “Creation of the Flat Tops,” (Oct. 29), the lava flows are mainly made up of limestone.

Actually, the lava that has hardened to rock is an igneous rock called basalt. Limestone is a sedimentary rock usually formed by chemical and biochemical precipitation on an ocean floor.



The limestone of the area, the Leadville Formation, is about 350 million years old. The basalt is about 10 million years old. Glaciation of the area began to decline about 10,000 to 12,000 years ago.

There must be geology books in the Craig library that could supply some accurate information.
