Montana Outdoors (magazine) articles with questions

I've been working with Montana Fish, Wildlife & Parks to write evaluations (worksheets) that go along with articles from their Montana Outdoors Magazine. Below is a list of articles and assignments that I have completed. Each worksheet includes teacher notes, possible bell-ringers, and an answer key. The assignments are best-suited for high school biology students or students taking environmental science.

Blowdown in SW Montana - aftermath of 2019 Microburst

On the afternoon of Sunday, August 11th 2019, a microburst occurred in the Tobacco Root Mountains of southwestern Montana, blowing down the estimated 200 to 250 acres of trees shown in the photo above. This blowdown resulted in the blockage of trails leading back to Granite Lake stranding 4 people in the backcountry due to trees blocking trails leaving the area. Personnel from the Madison County Search and Rescue, National Forest Service fire team, and two military helicopters were dispatched to the area to rescue those stranded in the backcountry.

The sky is falling!
So, why do microbursts happen? Like tornadoes, lightning, hail, and flash floods, microbursts are associated with severe thunderstorms. They’re caused by the same cooling effect that happens when sweat evaporates from your skin. As sweat evaporates, it cools your body because the water molecules absorb (and remove) heat when they change from liquid to vapor. The same thing can happen in a thunderstorm. As rain or hail falls through very dry air, or the thunderstorm draws in dry air, much (or all) of the precipitation may evaporate (called sublimation when hail changes to vapor). Water molecules absorb heat from the surrounding air to make this phase change, making the air much colder. The more evaporation, the colder the air gets. Anyone who has opened a refrigerator door knows that colder air is heavier than warmer air. As this air (cooled by the evaporation of rain, or sublimation of hail) gets heavier, it plunges toward the ground like a lead weight. When the microburst reaches the ground surface winds may exceed 150 miles per hour – strong enough to blow fully grown pine trees over. Interestingly, the opposite phase change (vapor to snow) releases heat, contributing to the warming effect that causes Chinook winds.

Mr. Tornado.
Microbursts were discovered in the 1970s by tornado scientist Ted Fujita who developed the famous Fujita scale for rating tornado intensity. No doubt, you’ve heard of an F5 tornado – the ‘F’ stands for Fujita. The scale was revised several years ago – now called the ‘Enhanced Fujita Scale’ (EF0 – EF5). Fujita proposed that microbursts were for real, and suggested they were responsible for a number of mysterious aircraft crashes that had happened in the past during takeoff or landing beneath thunderstorms. Confirmation of his hypothesis ultimately led to a reduction in aircraft accidents and saving of lives.

1943 Smith Mine Disaster near Bearcreek, Montana - 75 men died

A sign posted along the highway a few miles east of Red Lodge tells of the disaster that happened at this mine in the winter of 1943 . . .

Smoke pouring from the mine entrance about 10 o’clock in the morning of February 27, 1943, was the first indication of trouble. “There’s something wrong down here. I’m getting out,” the hoist operator called up. He and two nearby miners were the last men to leave the mine alive. Rescue crews from as far away as Butte and Cascade County worked around the clock in six-hour shifts to clear debris and search for possible survivors. There were none. The night of March 4, workers reached the first bodies. More followed until the toll mounted to 74. Some died as a result of a violent explosion in the No. 3 vein, the remainder fell victim to deadly methane gases released by the blast.

The tragedy at Smith Mine became Montana’s worst coal mine disaster, sparking investigations at the state and national level. Montana Governor Sam C. Ford visited the scene, offered state assistance and pushed a thorough inquiry into the incident.

The roadside sign that tells about of the disaster includes a message written by two of the miners trapped underground as they waited for the poisonous gas they knew would come.

Good-bye wives and daughters. We died an easy death. Love from both of us. Be good. Walter and Johnny.

The aftermath . . .

Several weeks after the disaster, a coroner’s inquest involving witnesses and mine bureau investigators concluded that some of the men died from concussion caused by a gas and dust explosion, while others fell victim to gas poisoning. The disaster had a huge impact on nearby communities of Bearcreek, Washoe, and Red Lodge. Fifty-eight women lost their husbands and 125 children became fatherless, including six of eight students in the senior class at Bearcreek High School. The disaster brought an end to the local coal mining industry despite the fact that thousands of tons of coal remain beneath the arid hills. The towns of Bear creek and Washoe all but vanished as homes were torn down, abandoned, or moved to nearby Red Lodge or Belfry. (source: Historian Bill Cenis, Town of Bearcreek)

Coal Use Then and Now . . .

Today most of the coal used in the United States is burned to generate electricity, with the next biggest share used in the production of steel. At the time of the Smith Mine disaster, coal was not used to generate electricity, but it did have many other uses that were important to the American way of life. One of the primary uses was for heating homes and other buildings. Coal trucks made regular deliveries to houses that were kept warm by coal-burning stoves, often located in basements. Coal also fueled the smelters that removed copper and silver from ores mined in the western part of the state. Large quantities were also used to power the railroad trains that shipped goods and people across the country and coal was (is) used to make steel, especially important in WWII. Locomotives burned coal until 1950 when diesel engines replaced steam engines, causing a drastic decrease in the demand for coal at that time. Coal’s other early uses have gone by the wayside as well, replaced by cleaner burning, more efficient fuels. Today the demand for coal is kept high by the demand for electricity to run our iPods, cell phones, video games, computers, televisions and other electronic devices.

Coal Mining Then and Now . . .

In the early 1900s there were many coal mines scattered in small towns across central and eastern Montana. Along with Bearcreek, Red Lodge, and Washoe, other communities such as Roundup, Klein, Belt, and Sand Coulee were also coal-mining towns. A big difference between coal mining in Montana at the time of the disaster and mining in recent decades is that “strip mining,” rather than underground mining, has been used to remove the vast majority of coal mined in Montana since 1970. With strip mining, layers of rock above the coal are removed to reach the seams of coal, and all of the work is done from the surface by large equipment operated by a few miners. Although it provides fewer jobs, strip mining is much safer because workers do not have to go underground where collapses, gas explosions, and lung diseadustses are risks.
