What snake is that? Arizona only. It picks only from the snakes that live where you're standing.

Every answer is a guess to satisfy your curiosity. It never tells you a snake is safe. Stay 6+ feet back from every snake.

Where will you be?

Your location picks which snakes live there. Only a rough spot (about half a mile) is sent once to look up the elevation; it is never stored.

Or pick a spot

Get the photo from where you are

Zoom in. Don't step closer to get a better shot. Getting the head and the tail in the photo helps most.

Stay 6+ feet back. Treat it as venomous.

Heard a buzz?

Hold still and let it listen. It tells you whether that sound is a rattle. It cannot tell you which direction it came from - a phone only has one microphone as far as a web app is concerned, and anything claiming a direction would be guessing.

Not listening
Tap start, then stay still.
Mic

Uses your mic to listen for a rattle. The sound is checked on your phone and never leaves it.

Back away from the sound. Do not walk toward it to test this. Straight from the recordings it was built on: it catches about 8 in 10 real rattles, and about 1 in 11 cicadas fools it. Treat a quiet reading as "no answer," never as "nothing there."

Trails near here

Trails from OpenStreetMap (ODbL). Length and climb measured from the trail itself; the difficulty word comes from the National Park Service formula, not from opinion. Check conditions and closures before you go - a trail can be washed out or closed and this app will not know. Mileage, climb and time are estimates.

Snake facts + safety

If this app says a snake is not venomous, treat it as venomous anyway.

If someone is bitten

Call 911 Poison Control
1-800-222-1222
Find the nearest ER

Treatment is antivenom, given in a hospital. The car ride to the ER is the first aid that matters most.

Do

  1. Move away from the snake. Don't try to catch or kill it.
  2. Call 911, or drive to the nearest ER now. Don't wait for symptoms.
  3. Stay calm and still. Keep the bitten arm or leg still, at about heart level.
  4. Take off rings, watches, and tight clothing near the bite before it swells.
  5. Note the time of the bite. Mark the edge of any swelling with a pen every 15 minutes.
  6. Wash the bite gently with soap and water and cover it with a clean, dry cloth.
  7. Take a photo of the snake only if you can do it from far away.

Don't

This is first aid only, not medical advice. Always get checked by a doctor or the ER. Poison Control is free and open 24/7.
