Yosemite bear-proof food locker latching systems

Each campsite in Yosemite, (as well as some trailheads, parking lots and some overnight accommodations,, has a metal food storage locker (bear box).

Most measure 35 inches deep by 43 inches wide by 28 inches tall, but you might still find some 33″ deep x 45″ wide x 18″ tall. Curry Village tent cabins have different sizes depending on the size of the cabin.

They are only bear-PROOF or raccoon-PROOF if people remember to keep them shut except when actually taking things in or out. Some people make the mistake of hanging a trash bag from the door.

Using a campsite food storage locker gives you ideas on how to use one, how to fit more things in a campsite bearbox, including some logistics on sharing one in a large group.

There have been many models of campsite / trailhead lockers, not all of which worked.

The original Yosemite bear boxes had two latches and people did not remember to latch / clip both, so animals more easily got into them. Next, most had a simple latch:

A newer model was slightly taller.

It had a handle you insert and turn.

When you turn the handle a latch at the top of one door opens or shuts.

A Yosemite Ranger (wildlife branch chief) told me about the history of the lockers:

“The locker with the hanging opener actually failed pretty quickly after it was installed. The bears learned to lift it with their mouths, insert it into the opening, and turn it. The retrofit was to have the opener hang on a chain so the bears couldn’t just swing it into place. We now exclusively buy the ones that you stick your hand up into the sleeve. That one has been retrofitted many times as well, but at this point has worked for years.”

That best model, also often seen in state parks, has you access the latch by putting your fingers into a metal slot on the outside of the door to the bearbox, and push upward. It will not work as well if you do not flatten your hand so your fingers can get fully in.

And again, a latch at the top of the door opens or shuts.

ALL MODELS are metal and are noisy when opened or shut. Unless you are careful you can wake up your neighbors who want to sleep earlier or later than you.

Bears can get into food storage boxes. Not just when people leave the doors open or partially closed for even a short amount of time, but also by trying to get closed doors to open:

“A large untagged/uncollared bear has been seen in Upper Pines and the Wilderness Lot, checking for improperly latched food storage lockers. Visitors have reported this bear going from site to site, banging on the locker latch. Unfortunately, the bear obtained food on at least three occasions from improperly latched lockers.”

Please use the clip on the trash bin to lock it. If a bear gets into a dumpster on a hot day it can be a death trap.

save a bear use the clip:

If you notice one is un-clipped, please clip it.
Immediately report it to a hotel front office, ranger or campground host if the clip is missing from the dumpster.

In the photo above, the note on it says:
“Dumpster Full
This dumpster is full and has been wired shut to prevent black bears from accessing the overflow trash. Please do your part in protecting Yosemite wildlife by finding another dumpster to dispose of your trash. Thank you.”

PLEASE, when a dumpster is full don’t just leave your trash sitting next to it, find another dumpster.

The Yosemite National Park rangers would like you to call them if you see a bear in Yosemite,
no matter where it is or what it is doing,
at 1 (209) 372-0322.

If you can, in all the excitement, try to notice if the bear has a tag (usually on the ear), the color of the tag and if possible, the number on it (the tag is large enough that with a telephoto you should be able to read the number).
