Not only is this a good skill to woo friends with but its useful in navigation and outdoors. Take a look at the following picture, can you tell how far different land features are? Here’s a general rule that works in areas with trees, you can use trees as a reference point for pin pointing the distance of other objects.
- You can see individual branches on trees at 1-3 Kilometers away (1-2 miles).
- At 3-6 Kilometers (2-4 miles) the human eye can pick out individual trees.
- At 6-9 Kilometers (3.5-5.5 miles) most people won’t be able to pick out individual trees in a group but the land will look like a shaggy carpet. Don’t look at the horizon but about 2/3 up the mountain.
- At 9-12 Kilometers (5.5 to 7.5 miles) the shaggy carpet turns to an industrial smooth carpet.
- At distances greater than 12 Kilometers (8 miles) the forest looks like a blue haze.
Take another look at a different picture, can you pick out the distances now?
