The weather in Grand Teton National Park can be highly variable, especially in late spring and summer. June often brings mild daytime temperatures ranging from the 60s to low 70s Fahrenheit, while nighttime temperatures can dip into the 30s and 40s. Snow may still linger at higher elevations, and alpine trails may remain partially covered. As the summer progresses, the park generally experiences clearer skies and warmer temperatures, though mountain weather can change rapidly.
Thunderstorms are a common occurrence in the afternoons, especially from late June through August. These storms typically build quickly due to the intense summer sun heating the mountain slopes, creating updrafts that lead to cumulonimbus cloud formation. Lightning, strong gusty winds, and sudden downpours can accompany these storms, posing risks to hikers and climbers above the treeline or on exposed ridges. Visitors are advised to start hikes early in the day and plan to be off high ground by early afternoon.
Despite the risks, thunderstorms add dramatic beauty to the Tetons, with striking cloud formations and the deep rumble of thunder echoing off the peaks. However, safety is paramount. It’s essential to monitor local forecasts, carry waterproof gear, and seek lower ground at the first signs of thunder or darkening skies. The grandeur of Grand Teton’s weather is part of its allure—but it demands respect and preparation.
A view of an early summer corn crop growing on a farm in Mt. Vernon (Posey County), Indiana.
History of Corn in America
Corn (maize) has deep roots in American agriculture, dating back thousands of years to Indigenous civilizations such as the Mayans and Aztecs. Native Americans domesticated corn over 9,000 years ago, developing hundreds of varieties suited to different climates and growing conditions. When European settlers arrived in the 1600s, they learned corn cultivation techniques from Indigenous peoples, helping them survive and establish agriculture-based economies.
By the 19th century, corn became a staple crop across the Midwest, aided by the expansion of railroads, new farming equipment, and scientific breeding techniques. The introduction of hybrid corn in the early 20th century dramatically increased yields, making the U.S. the world’s largest corn producer.
Political Influence and Economic Impact
Corn is at the center of U.S. agricultural policy, heavily influenced by government subsidies, trade agreements, and biofuel mandates. Key political factors include:
Farm Subsidies: The U.S. government provides billions in subsidies to corn farmers, ensuring price stability and encouraging high production levels. The Farm Bill, passed every five years, plays a crucial role in shaping these policies.
Ethanol Production: The Renewable Fuel Standard (RFS) requires a portion of gasoline to contain ethanol, which is primarily derived from corn. This policy has fueled corn demand, increasing both prices and environmental concerns.
International Trade: The U.S. exports a significant portion of its corn to countries like Mexico, China, and Japan. Trade agreements and tariffs can heavily impact the corn industry, as seen in the U.S.-China trade war that led to volatile corn prices.
Challenges Facing Corn Production
Despite its economic importance, growing corn in America faces several challenges:
Environmental Concerns:
Corn farming is resource-intensive, requiring high water use and synthetic fertilizers that contribute to water pollution.
Monoculture farming depletes soil health and increases vulnerability to pests and diseases.
The expansion of cornfields has led to deforestation and loss of biodiversity.
Climate Change:
Rising temperatures, unpredictable rainfall, and increased droughts threaten corn yields.
The shift in growing seasons forces farmers to adopt new techniques and invest in drought-resistant crops.
Market Volatility:
Fluctuating corn prices due to global supply and demand, weather conditions, and geopolitical events can impact farmers’ profitability.
Overproduction can lead to price crashes, affecting small farmers more severely.
Technological and Biotech Controversies:
The widespread use of genetically modified (GM) corn has raised debates over health and environmental risks.
Pesticide-resistant pests and herbicide-resistant weeds have emerged as a challenge, leading to greater reliance on chemical inputs.
Shifts in Consumer Preferences:
Growing concerns about processed foods and high-fructose corn syrup have affected domestic demand.
Alternative protein sources and plant-based diets may reduce demand for corn-based animal feed in the future.
Grand Teton National Park which was established in 1929 by President Calvin Coolidge, is located in the Jackson Hole valley of Wyoming. It is connected with Yellowstone National Park to the North via the John D. Rockefeller, Jr. Memorial Parkway. The park owes much of existence to Rockefeller, who believed so strongly that the Jackson Valley needed to be preserved, that he purchased large portions of it, before turning control over to the Federal Government for conservation.
Summer weather in Grand Teton National Park is generally mild and pleasant, with warm days and cool nights. From June through August, daytime temperatures typically range from the mid-60s to the mid-80s°F (18–29°C), while nighttime temperatures can drop into the 30s and 40s°F (0–10°C). Afternoon thunderstorms are common, especially in July, bringing brief but intense rain, lightning, and occasional hail. The park’s high elevation means that even summer mornings can be chilly, so layering is recommended for outdoor activities. Despite occasional rain, summer is the best time for hiking, wildlife viewing, and enjoying the park’s breathtaking landscapes.
