Slide1

Do you know what’s going on in Timpanogos Caves?By: Diantha Smith, 2009

Cave Basics

Slide2

How did fossils get in the caves?

The fossils show us that Utah was once part of a shallow sea where fish and other sea creatures lived.When the creatures died their bodies floated to the bottom and after a long time huge layers of shells, plants and organisms built up.

All those layers smashing on top of each other made the sedimentary rock limestone.

Timpanogos Cave is in a layer of Deseret Limestone.

Slide3

What made the holes in the rock?

As the continents shifted northward, huge plates of rock smashed together forming mountains and new fault lines.Water flowed into the faults from underground lakes and/or rivers.

Water picked up carbon dioxide from the air or from plants in the ground and made a weak acid called carbonic acid.

Carbonic acid ate away the rock until it created an opening to the outside air.

Slide4

How did the caves get so high?

Pressure built up along the fault lines and the land began to uplift.The cave was pushed higher and higher in the mountains.At the same time, the river cut the canyon deeper and deeper.

The mountains are continuing to grow higher, but erosion is breaking them down at the same time.

Slide5

How does water shape the rocks in the caves?

What lives in caves? Not TICA specifically

Slide7

What is the future of the caves?

Formations grow slowly, but as long as water is moving through the cave they will get bigger and bigger.Stalactites and stalagmites grow together to make columns.

Eventually the entire cave

may

fill up with calcite.Or the outside rock may erode away to expose the cave.
