Hello everyone, about 5 years ago, while at house keeping tents at Yosemite, we had a small bear come in and grab a backpack (which had a small sandwich). It was bit scary in the middle of the night. Obviously, I know it was our mistake.

I have seen a video of someone having an encounter with a large bear at Whitney portal camp grounds at night.

It seems keeping food in bear containers is best way to keep the bears at bay. Are there any other ways to keep them away? May be keeping the lantern on or keeping a fire on, etc? What are best ways to keep them away without stressing them out.

Also, how common are bear encounters at Whitney Portal?

Thanks!
