The Sierra National Forest is densely populated with trails. The seven zoom layers of the map prevent it from turning into trail spaghetti. There are hundreds of dead end spurs that you will only see if you zoom into the lowest level. They range in length up to a half a mile or more. In other areas of the map, spurs of these lengths might normally be displayed at a higher zoom level because there isn't much else in proximity. Many trails in the Sierra National Forest will appear at a lower zoom level to provide clarity at higher levels.
