Quick Answer
When hiking in flood-prone areas, look for high ground spots at least 100 feet above the lowest elevation point in the area, ideally on ridges or hilltops with stable terrain. Avoid low-lying areas and narrow valleys. High ground spots can be identified by observing the natural terrain features such as ridges, hilltops, and rock outcroppings.
Identifying High Ground Spots
When searching for high ground spots, pay attention to the shape and orientation of the terrain. Ridges, which are long, narrow hills with a gentle slope on one side and a steeper slope on the other, are ideal locations for high ground spots. These ridges often create natural channels for water to flow through, making them safer during flash flooding.
Elevation Considerations
When selecting high ground spots, it’s essential to consider the minimum elevation required for safety. As a general rule, aim for areas at least 100 feet above the lowest elevation point in the area. This elevation difference can help protect you from flash flooding by reducing the risk of being swept away by fast-moving water. In areas with a history of severe flooding, consider a higher elevation, such as 200 feet or more above the lowest point.
Terrain Stability and Safety
In addition to elevation, high ground spots should also have stable terrain to ensure safety. Steep slopes, loose rocks, and unstable soil can increase the risk of landslides and rockfall, making it harder to navigate during a flash flood. Look for areas with stable terrain features such as rock outcroppings, ridges, and hills with established vegetation.
