This thread is for comments on the article "How to Hang Your Bear Bag: Tips from Leave No Trace"

Know how to hang a bear bag properly in the backcountry and keep bears (and your food) safe? Leave No Trace gives a refresher on this essential skill.

i have generally had more success with the two tree method.  for throwing the rope over a branch, i discourage using a rock.  use what you have with you - tie a short loop in the end of your rope, attach a carabiner, and attach something else that has some weight - for me, it's often a chaco or a keen water shoe that has enough weight to be chucked over a  branch. 

provided you have enough utility line, i suggest securing each end to something other than the two trees on each end of the system.  reduces the risk that a bear will take down the system by biting or clawing through the rope. 

because some bears know and are not defeated by bear bags, bear cannisters are the safer option.  in my opinion.

Anyone know the highest elevations black bears will ascend to for food? I was bear-bagging in the San Gorgonio Wilderness in SoCal at 10,200 feet. Some guy told me that I didn't have to worry about bears at that elevation, that bears had only been reported in that region at up to 7500-8000 feet. I figured better to be safe than sorry...

Do bears venture about tree-line?

Here in the eastern mountains, there are usually lots of hardwoods with large, long branches that are perfect. It gets trickier with evergreens and tall, smooth bole trees like yellow poplar.

I have learned that a rock in a small nylon stuff sack works the best. Other objects tend to get hung up in the branches too easily. Sometimes it is necessary, or at least advantageous, to pull the weight back up and over one or more branches. The rock-in-a-stuffsack option works great, especially if you use a nice smooth stone. 

One thing that wasn't mentioned is how to handle heavy loads, as a line will saw and dig down into a limb, even so badly as to get stuck. If you are in a largish group, it is sometimes not practical for each member to hang their own line. to do this you use two lines: one to suspend a carabiner that acts as a pulley, and one to hoist the load. The fulcrum line is raised and secured without being loaded, which won't damage or bind on the limb, and carabiner "pulley" makes hoisting the loaded line a breeze. 

Xterro,

I do not know how high they will venture. But I would think they are likely to go as high as trees and shrubby vegetation will grow. If not using a canister, it would seem prudent to hang if there are trees to do so. 

While I was in the Tetons last year, I saw three blackies, at 9,500, 9,200, and 9,400ft, respectively. The first one was descending from a shelf a few hundred feet up, and the other two were ascending towards treeline. 

Xterro,

While I can't comment on San Jacinto, I have some very nice pictures of bears in Sequoia/Kings Canyon at 10k+.  Even if bears won't go that high, other four-legged critters will, which makes me think that hanging food is a good idea.  Personally, I've moved to carrying a canister whenever I hike.  It's mouse-proof (something a bear bag isn't, as was demonstrated to me in the Smokies one year), and it means I don't have to worry about finding an acceptable pair of trees at dusk after hiking all day.  To me that's worth the extra two pounds.

Do bears venture about tree-line?

 When I lived in SoCal and hiked, skied, and climbed a fair amount in the Greyback and SanJac areas, we did see bears from time to time crossing at the Dollar Lake Saddle (abt 10k) and around the stone hut on San Jac (back when we were allowed to stay at the hut, 10.5k or so, though that was before the tram). On the SanG side, that is above timberline, but treeline on SanJac goes up to the summit. We were told by the rangers at the time that there were several saddles that the bears would cross from N-S and reverse along the Greyback crestline, though the ones I recall were pretty much following the trail across Dollar Saddle. There seemed to be 2 or 3 that hung out around Dollar Lake (we could camp there at the time) and Dry Lake, maybe because they were popular campsites. And don't forget - Big Bear Lake got that name for a reason.

Not like on Denali, though, where we saw griz tracks on the upper Kahiltna Glacier. In the required pre-briefing, we were told that it was not unusual for the brownies to migrate over the pass between the northern and southern parts of the range (Peters Basin to the north, Kahiltna Glacier to the south) via Kahiltna Pass. There used to be a photo from a plane of one almost at the pass on the wall at the ranger office in Talkeetna. Big question I had was how the heck did they avoid the crevasses, especially on the lower parts of the glaciers. Problem on the Kahiltna was ravens digging down in the snow to get at the food caches, not the bears.

If you watch the programs on the NatGeo, Discovery, PBS, Nature channels on bears in the Canadian Rockies, you will see that they root around in talus fields to go after some variety of moth larvae, well above timberline.

But, yes, mice, marmots, and raccoons are very good at taking down bear bags or tearing into them. Canisters work well for them as well as bears.

As always, gentlemen, your wisdom and insight is most appreciated. I'm very glad I asked. A bear cannister purchase looms on the horizon...

I like 20-25ft personally:

We've found that it is a good idea to use reflective paracord or tie some reflective tape to your bear-bag line.

I lost count of the number of times I struggled to find our line in the dark before we started doing this.

Do bears venture about tree-line?

Here is a aritical that states that both grizzlies and black bears will venture above tree line.  My guess is that if a bear is hungry it will go anywhere it can to get food.  Including your fridge if your house is not strong enough to keep it out.

"At these places of slide rock and sunshine, both grizzly and black bears gather each year, climbing high above timberline to feed on the moths."

This adaptation of the two tree method reduces damage to trees since a weighted rope is not dragged over bark, and is adaptable to other terrain objects.

camped past bishop pass in the sierra about ten years ago. elevation over twelve thousand feet. there were two bears, one before the pass and one after. well above treeline, the bears were very active, even stealing the pack of one unfortunate hiker...they eventually got it back, minus some food with a few holes in the pack. definately invest in a bear can, go with a bearikade. we had bear cans and as soon as the bear saw them he went the other way. He knew he wasn't getting anything out of this group.

Very interesting. I hike and camp up on San Jacinto every summer for a couple three days and never give bears a though. Last time I talked to a ranger (other than for getting a permit), I recall him saying there were no bears on the mountain. No one up there, that I've noticed, hangs food or uses canisters.

I have see what I took to be bear scratchings on trees around both Big and Little Round Valleys, up there in recent years.  Do not recall if I saw such evidence decades ago, however.

Interesting, Ed.  I have a friend whot works up there.  I'm going to ask him for the latest.

I heard from my friend about bears on San Jacinto.  Here's what he said:

"As far as I know there are no bears. I have never seen or heard of any bears or evidence of bears at least near the tram or round valley. Mountain lions yes.

I did recently hear that there was black bear sighting near Idylwild, but that was from a guest.

A few years ago the State released a black bear at the Valley Tram station. They just let it go in the employee parking lot without asking us. It wasn't seen again.

Also a couple of years ago a black bear was seen in the desert around I-10, probably wandered out of whitewater canyon."

Interesting about the mountain lion and the black bear being released in the parking lot!

The first time I tried a two branch hang the rock flew over the branch and then swung right back at my head. Missed me by a foot. Learned my lesson quickly.

The article mentioned having a 'helper' to raise the bag. Obviously, if you're solo you can just tie off one end after you've thrown the rock over the first tree. Stretch it taught so you can get a better idea of where to make your loop for the bear bag. You'll want to position it so when you raise your bag it's right between the two trees.

Bears travel where ever there is a food supply for them.  Learn to recognize bear habitat, then you won't have to wonder.  Sometimes there are available food items that are not so obvious like the whitebark pine seed harvest at treeline, or moth hatches above treeline in Yellowstone.

The best bear habitat always has cover, lots of shrubs, grass and grass-like plants and forbs like false-hellebore (skunk cabbage).  Open country and dense forest provides relatively little in the way of food for bears.  When  there is any doubt, hang your food.  Never sleep with it no matter what.  As time goes along bear cannisters will become required more and the old hanging techniques will fade from memory.

I hike in Canada and the northeastern United States (Maine and New Hampshire primarily). Hanging food to keep them from the Black Bear is effective using either of the methods. The bears seem to always go where there is plentiful easy food, so if they have to work for it usually not interested is what I find.

Looking for suggestions on the elusive relentless eastern red squirrel who will run down my rope and gnaw his way through the sacks and take up residence in the sacks til morning when he is chased out, leaving with a full belly. Looking for suggestions on how to make hime go somewhere else for a snack.

Carry an empty soup can with you poke a hole in it and put it on your rope that hangs down. Like in some of the at shelters. Ive seen people put the open end up or down both seem to work. If they get past that cut a 10 inch circle of sheet metal, poke the hole and do the same hanging thing. If the get past the metal, carry some birdseed, go back to the can, hang it open end up filled with the seed. Not the best ides to feed them but it could save your food and your sack.

Unless you are competent enough to consistently employ the COUNTERBALANCE METHOD *effectively* I highly recommend getting a canister. Bears in many locations have figured out tie-off hanging to say the least.

I like the canister here in the GYE. We don't have a lot of deciduous trees in many desireable camping locations and as noted Evergreens present more challenges.

I will not use an ursack.   

What if the bear doesn't want his bag hung? :)

As others have noted, bears go where there is a good supply of food. This can come in many forms and at different times of the season. The most obvious is when the bears here in the NW move to the high alpine slopes in late summer and fall to eat the berries. I will add that food sources take a backseat to cover. Most of my PNW bear encounters are in more open country. Two months ago I encountered a young black bear foraging in slopes in the alpine above Chinook Pass. Prey animals will also attract bears, specifically grizzlies. In the Northern Rockies and elsewhere with grizzlies, dug up marmot and sik sik dens are a sign of bears. Overturned rotten logs can also be a sign of bears. Canisters have become the norm in high human/bear encounter areas. If there is less likelihood of an encounter, hanging works well. In areas where bears are not habituated to humans, hanging, or even simply using a plastic sealed container stuffed in a rock crevice will avoid a bear encounter. Understanding bear behavior is important to avoiding negative experiences with them. In my Barrens and Arctic trips, there is no place to hang and canisters would be impractical to carry a month's worth of food. The standard method is to put the food containers away from any game trails and shorelines, and in something like an alder thicket.

Erich,

We would love to hear more about your trips to the Barrens.

I have cached my food before with lots of pots and pans on top.  I usually camp with a pack of dogs which are the first line of defense.  Some people don't like this idea, but it has been very effective in chasing bears out of camp.

I have fond memories of glissading at Chinook Pass in the summer.

All of the National Parks in California require bear canisters...and since we bought one to use in those parks, we now use it everywhere.  It works.  i don't have to worry about taking along my dogs, bear bags left in trees, hoping bears don't smell buried caches, etc. 

ppine, Anywhere in the Far North is spectacular, and not what most people expect. Bugs CAN be a problem(forget the bug net Andrew Skurka, go for the original Bug Shirt), many areas and times of year are relatively bug free. What i find most intriguing, is the diversity of the landscape. I recently read a story about a journalist who was invited on a guided trip on the Mountain River. She is from Ontario and was surprised at the mountain ranges and deep canyons. Few people south of the US border, know that the Nahanni was the first Unesco World Heritage site in the Western Hemisphere, or that the Yukon was unglaciated in the last ice age. Flying over these areas, one wonders at the vastness of relatively untouched natural lands. But, unfortunately, much of it is under attack from mining and petroleum interests. The site at Tungsten in the YT, sits just outside the Nahanni Park, and the entire Peel drainage is unprotected. The great herds of Caribou in the western Barrens will likely disappear in the next twenty years because of impacts from development.

Dogs can certainly deter some bears. However, in grizzly country dogs will often attract bears.
