How did the weather impact Lewis and clark expedition?

- The expedition faced several harsh winters during its journey, particularly in the northern plains and the Rocky Mountains.

- The cold weather made traveling and camping difficult, leading to frostbite, hypothermia, and other illnesses among the expedition members.

2. Snow and Ice:

- Heavy snowfall and icy conditions often blocked mountain passes and made it challenging to traverse through rugged terrains.

3. Spring Floods:

- In the spring, melting snow caused rivers to swell, making them dangerous to cross.

- The expedition had to wait for the floodwaters to recede, resulting in delays and the need for alternate routes.

4. Summer Heat:

- During the summer months, particularly in the Great Plains, the expedition encountered extreme heat and drought conditions.

- The scorching sun, coupled with limited water resources, posed challenges to both humans and animals.

5. Forest Fires:

- Wildfires were a significant hazard, especially in the western regions.

- Smoke and flames hampered visibility and made it difficult to navigate through forests, increasing the risk of accidents and animal encounters.

6. Impact on Wildlife and Vegetation:

- Severe weather conditions affected the availability and accessibility of food resources, such as wild plants and animals, which were essential for the expedition's sustenance.
