There are a lot of terrible things happening in the world right now. People around the planet are worried about politics, war, diseases and illnesses, catastrophes, and the general litany of concerns brought on by life, work, school, and home. It can be overwhelming. Sometimes, you just need a break, if only to replenish yourself for the next round.

Even if you can’t get away from it all physically, you can take a quick mental vacation to appreciate the incredible planet on which we live. While viewing nature on a screen isn’t necessarily a substitute for the real thing, it can help you relax—even if you’re in a particularly stressful situation.

Here are some gorgeous images from the wilderness and parks of the United States. Happy Earth Day!

It’s easy to see where the Red Cliffs National Conservation Area in Utah gets its name. The Conservation Area is part of a larger reserve of the same name, which aims to provide a safe habitat for the threatened Mojave desert tortoise, in addition to recreation areas for visitors.
