Exploring Geoheritage Through EarthCaching

An EarthCache is a special site that people can visit to learn about a unique geoscience feature or aspect of our Earth. Visitors to EarthCache sites can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.

Exploring Porosity

Earth scientists play a vital role in harvesting the energy resources on which we all rely. When preparing to drill for oil, for example, geoscientists must assess many aspects of a rock stratum (layer). For example, they must figure out the volume of the rock’s pores, or empty spaces, as compared with the rock’s total volume. This is called the rock’s porosity. To help you understand porosity, think about different sizes of gravel. Which size gravel will have the greatest porosity? Why? In this activity, you will work in groups to explore the answers to these questions.

Exploring Your Community

Think about the weather and environment where you live. Have you ever been in a strong storm? Have you ever experienced flooding, a wildfire, or really hot days? These types of environmental hazards are happening more often because of climate change. Even though these events can be scary, there is so much you can do in your own community to make it better able to handle these challenges. When we work together to protect our communities from environmental hazards, we are building community resilience.

Find Your Park

A park can be many different things to many different people. For many people, Canyonlands National Park is a favorite showcase of geology.

In each of the park’s districts, you can see the remarkable effects of millions of years of erosion on a landscape of sedimentary rock. The Green River has carved a channel out of rock layers deposited nearly 300 million years ago creating an open book for earth science enthusiast of all ages.

Finding Slope

Explore how the slope of land will effect water flow and life above ground in this activity from the Soil Science Society of America.

Flood!

Learn the dangers of flooding in this activity, where students explore soil porosity and permeability.

Food Source

How diverse are the food sources in your community and where are they located? How far do they travel to reach you? Do you think the food sources for your community are sustainable? This multi-day activity explores these questions.

Fossil Formation

Have you ever seen a fossil? A fossil is any evidence of past life preserved in sediments or rocks. Do you think you could have dinosaur fossils in your family car’s gas tank? Did you ever hear that oil and natural gas are “fossil fuels”? Do you think oil and natural gas can be made from fossils? How long do you think it takes fossil fuel to form?

Freddy the Fish

Human activities can have a detrimental effect on animal habitats. Young students can witness the effect of water pollution on river habitats.

Frozen Power

You may be familiar with ice cubes in your favorite soda, but do you know there are very big ice cubes (scientists call them glaciers) hundreds to thousands of meters thick, lying in places
with high mountains? These glaciers shaped beautiful landscapes all around the world — from Glacier National Park to Yosemite, from Patagonia in South America to the Himalayas in Asia.
