Key Details of the 1930 Columbia River Freeze
The freezing of the Columbia River in 1930 was a rare and significant meteorological occurrence, characterized by severe winter conditions. Below are the key aspects of this historic event:
| Aspect | Description |
|---|---|
| Date | January 1930 |
| Duration of Freeze | 19 days of below-freezing temperatures |
| Temperature | Temperatures often fell below zero |
| Snowfall | 23 inches of snow accumulated |
This intense cold snap, combined with heavy snowfall, led to the formation of thick ice across the river's surface, a sight rarely witnessed on such a major waterway. The Columbia River is one of North America's largest rivers, flowing from British Columbia through Washington and Oregon before reaching the Pacific Ocean. Its freezing is a testament to the severity of the 1930 winter.
