Caves and Caverns

When I was growing up in Kentucky, my family visited Mammoth Cave and when I was teaching science, I chaperoned field trips to the Dahlonega Gold Mines. Click here for further information and photos of this field trip.

Because my husband and I couldn’t continue our journey to Glacier National Park, we explored some sights near Bozeman, Montana. One of those day trips led us to Lewis and Clark Caverns State Park.

The Lewis and Clark Caverns, Montana’s first state park, became federal property in 1908. Although they never entered the caverns, the park was named after Meriwether Lewis and William Clark whose expedition passed through the area as they explored the western portion of the United States after the Louisiana Purchase. These caverns are unique because they are high in the mountains.

What is the difference between a cave and a cavern?  Caverns consist of a series of caves connected with one passage, while caves tend to consist of only one hollow.

We hiked to the entrance of the caverns. Although the outside temperature was nearly 80 degrees, the temperature remains approximately 48 degrees Fahrenheit inside the caverns.

The cathedral room was spectacular! The most common features were dripstone (soda straws, stalagmites, stalactites, and columns); flowstone (canopies, waterfalls, and cave bacon); and seepstone (cave popcorn and helicities).

I was hoping to see the resident Townsend’s big eared bats, but no luck on this visit.

Look at what this teacher did to transform her hallway and classroom! Crumbled brown paper makes it appear as though you are inside caverns. Use a cave unit to kick off a study of bats or bears. If you want to integrate art into a cave unit, make cave paintings

Wolves in Yellowstone

By the early 1900s, wolves were disappearing due to loss of habitat and extermination programs. The gray wolf was listed as an endangered species in the 1970s by the US Fish and Wildlife Service. In response, the Yellowstone ecosystem was designated as one of the recovery areas. Click here to learn more.

Scientists continue to learn more about how living and nonliving things are interdependent. In 1995, fourteen wolves were released in the park and the changes to the ecosystem were unexpected. This is one of my favorite videos. Click here to watch full screen.

Grizzly Bears

When my husband and I were in Yellowstone and the surrounding areas, we were frequently reminded that encountering grizzly bears was a real possibility and warned not to hike without bear spray.

I saw two bears from a distance but was unable to photograph them. These photos were captured by my friends, Susan and Ted, who live in Montana.

Felt as if I was on a bear hunt which reminded me of one of my favorite children ‘s books. This story is easily dramatized and it’s always fun to add sound effects using your body, common objects, or instruments. Use this book as an engaging way to teach positional words (under, over, and through) as well as descriptive words (long and wavy), and onomatopoeia (sound words). I have made a map of this story on a long sheet of bulletin board paper with prior classes to introduce map skills and to retell and sequence the events.

Bison

Finding buffalo in Yellowstone is almost certain, and I was anxious to see them. It is the only place in the United States where bison have lived continually, and they roam and migrate freely as they graze on grasses and other plants.

Bison were declared the national mammal of America in 2016. There are also European bison.

The history of the bison is a heartbreaking one. I’m grateful for conservation efforts that have saved the buffalo from extinction. Click here to view full screen.

A sweet story to add to your collection:

I found myself singing,
Oh give me a home where the buffalo roam,
Where the deer and the antelope play,

Note: The first two photos were taken by my friend, Susan.

Continental Divides

The Continental Divide, which runs along the Rocky Mountains, separates watersheds in the contiguous 48 states of America that drain into the Pacific or Atlantic Oceans. The Great Divide stretches from Alaska to the tip of South America and runs through the states of Montana, Idaho, Wyoming, Colorado, and New Mexico.

Forest Fires

Our original vacation plans were to travel from Livingston to Missoula and then onto Whitefish, Montana and Glacier National Park. However, the smoke from forest fires burning in several states prevented us from accomplishing our plans. The air quality was just too poor.

The debate on whether to extinguish forest fires, often caused by lightning strikes in Yellowstone National Park, was an interesting one. In the past, attempts were always made to put out fires in the park, but thoughts have changed on whether that is the healthiest choice for a thriving ecosystem. The National Park System permits lightning-ignited fires to burn in Yellowstone if they are not a threat to human life or property. Yellowstone’s fire season usually lasts from July through late September.

Lodgepole pines fill the forests of Yellowstone. The cones of these pines are tightly sealed with resin. As a result, the cones can’t open unless they’re exposed to very high temperatures, like that of a forest fire. The cones may be on the trees for years before there is enough heat to open them. Can you see the saplings in the photo below? Dead and burned trees are not removed because they provide food and shelter for animals and nutrients for the soil. These tall, straight pines were used to construct tipis by native people, hence the name lodgepole pine.

We were told by rangers that many large animals, like elk and moose, benefit from the open spaces created by the fires. By removing the forest overstory, fire also promotes habitat diversity.

There is a time for everything, and a season for every activity under the heavens. (Ecclesiastes 3:1)

Thistle

I discovered thistles growing in the fields of Wyoming and Montana. These plants are covered with prickly leaves and stems which protect them from herbivores, but thistles are still valuable to animal life. Pollinators extract nectar from their flowers, and birds eat the seeds and use the down for nests. I’ve always thought thistles were enticing, but ranchers and farmers think of them as troublesome weeds that are difficult to remove because of their prickles and stubborn root system.

Magpies

On a recent trip to Montana and Wyoming, I saw magpies for the first time. They were everywhere and since I knew very little about this species, I did some research.

Magpies are about 18 inches long and are easily recognized by their black and white plumage. Wings and longs tails are iridescent green, blue, or purple. Magpies, related to crows, are omnivores and eat a varied diet. They are thought to be intelligent animals capable of complex thinking, A group pf magpies is called a parliament. Magpies mate for life and females lay about six eggs per clutch. Click here for additional information.

Birch Trees

I grew up in New York and loved the white (paper) birch trees. I saw them again on a recent trip to Montana. Although there are 60 species of birch trees, paper birch trees, deciduous hardwoods, are easily identified by the peeling white bark. Brainstorm why the trunk may have black markings with your children or students. These black streaks are lenticels and help gases move between the air and tree. Birch trees grow quickly but are short-lived. They often have multiple trunks and prefer moist habitats. Native people used sheets of bark to cover canoes and wigwams.

Leaves have double toothed margins and turn yellow each autumn.

The small dry fruit grow in clusters on drooping catkins that turn brown as they mature.

There are simple ways for students to create birch trees, like the ones below made by Mrs. Lilge’s PreK class. Place painter’s tape on your paper to form the outline of the birch trees. Press the edges down well. Older students may want to place some trees in the foreground and others in the background after drawing the horizon. Design trees of various widths by overlapping the tape. Remove the painter’s tape after blending paint across the paper and over the tape to create a sunset. Add the lenticels to complete the trees with a black marker or crayon. Note: Blend paint for the sunset with three colors, such as orange, yellow, and red, or blue, purple, and red.
