I am doing a 3 day trip down into the Grand Canyon second week of september and I have heard there are lots of little cirtters down there. Is a Ursack s29 an appropriote protection for food against the little buggers?Jul 13, 2007 at 10:57 am #1395300Aaron WallaceBPL Member
You can email Tom Cohen at Ursack for more definitive information, but as I understand it small rodents have been known to be able to chew through some Ursack fabrics. The S29 is probably too new to have much field experience in this regard, but it appears like it would be much more critter resistant than the previous Vectran (Vxx) Ursacks.Jul 13, 2007 at 11:27 am #1395303kevin davidsonMember

You do need to use the Ursack with odorproof bags. I haven't had any rodent issues w/ mine in the PNW and Sierra in the 3 years I've used one—I have the sage green Spectra fabric model.Jul 13, 2007 at 12:12 pm #1395311Scott WhiteMember

The established campsites where I camped in the Grand Canyon this spring all had ammo boxes available for food storage. However, I was camping along the main trails: North Kaibab, South Kaibab, and Bright Angel. If you are heading to more remote areas of the canyon this may not be the case.

I am going to be headed down the Hermit Trail and crossing over to Bright Angel via Tonto. Camping the first night at Monument Springs campsite. Looking at the information I received with my permit it stated that all food containers were removed. I some pictures I saw stands that look like you can hang your food from but I do not want to depend on that.
I appreciate the feedback guys, hiking in the desert is completely new to me.Jul 13, 2007 at 12:42 pm #1395316Jason BrinkmanBPL Member
I'm personally interested in learning more about desert hiking, so please feel free to expand this topic. Would like to explore UT, NM, AZ, NV for spring hikes before the mountains open up.
I have a V27 Ursack that I use some, but no killer rodents here, so can't help with that.
Had a marmot try to eat my water bladder in the Beartooths last year. Bad marmot. Eat rocks.Jul 13, 2007 at 1:02 pm #1395319
I agree that Desert hiking is somthing I have been trying to read up on. He is my gear list so far. I am going the second week of Sept so it will still be mighty home. On my second day I will be traveling from Monument Creek campsite to Bright Angel. From what I have read there is very little to no water so I will be carrying around 2 gallons of water as a safety precaution since I do not know what to expect.

I don't remember any critters at monument campground the two times I have been there, 2002 and 2004. At Bright Angel campground turkeys sometimes find their way to bother you though.Jul 13, 2007 at 6:37 pm #1395346Doug HileMember
I hike in the Big Ditch a couple times a year. Mice are the biggest problem, I'm not sure how well the ursack works against them. The next critter to cause a problem is the ravens, I have heard of them opening zippers on packs.
Ringtail cats (a desert raccoon) can be trouble, one ran in while I was packing up before sun rise and grabbed a bagel that I was eating for breakfast while packing up. I had just set it down on a rock and turned to push something in my pack, he was in, got it, and gone that fast. I saw him in mid air on the way in and nothing that I could do. My food stays in hand now.
I use a ratsack from armoredoutdoorgear.com they work but are a bit heavier.
On the corridors trails there are ammo cans but that is it. They used to keep them at more campsites but people were leavening trash in them and critters were getting trapped in them as they need to be left up side down.Aug 4, 2007 at 2:24 pm #1397417Colleen ClemensMember

i have personally witnessed GC ravens unzip pack pockets, although i didn't realize that was what they were doing at the time – they were perching and pecking on packs at an unattended campsite next to ours, but i had no idea then what they were capable of. when the neighbors returned, they reported to us that their pack pockets (externals) had been unzipped and it appeared that the ravens had pecked through the food bags and had a feast.
in treed areas of the GC, also watch out for the squirrels. they are clever and determined and will chew through packs.Aug 11, 2009 at 7:58 am #1520047
I know this thread is old. There is a new product sold at Grand Canyon. Its called "outsak" and its a rodent proof bag sold at the stores along the south rim. I was skeptical when it was recommended to me, thought it was another nickel and dime situation, wanting to squeeze me for $$$. $25 to get in the park after paying for a permit and hotel reservation. Sorry, still burns me up how much they charge to get into a park after you have already spent so much for a backpacking trip.
Done ranting. Outsak saved my food on the second night of my trip in May 2009. I was 2 days in, 4 days to go on the trip and some sort of animal attempted to get my food. The Outsak stopped them cold. I had my food inside ziplocks, inside a nylon bag, inside the outsak. There were a feew spots where animals pulled on the wires, they nibbled the nylon bag a bit, but couldn't get far enough in to get at the ziplocks. Layers of protection, i guess are the key. If they would have gotten my food, I would have had a two day walk to get out on very little chow. Even if an animal chews a corner of a bag, that meal is gone in my book, especially in Grand Canyon, with the disease these rodents carry.People have died from exposure to these diseases, and recently. At least one in 2008, and one in 2009. Not the way to end a backpacking or river trip.Aug 11, 2009 at 8:15 am #1520051Greg MihalikBPL Member
Outsak can be found Here.
$33, $40, and $45 for S,M, L
I have had a RatSak save my food on many occasions and it's nice to see something similar.Aug 11, 2009 at 8:47 am #1520060
the older generation of OUTsack had durability issues and ravens could get inside. Im not sure about the newer gen. of OUTsack but these Grubpacks are basically the same thing.
its not only the mice that can ruin a trip but the Ravens will destroy anything and they hang out where the people feed them.. so dont feed GC animals, no matter how cute they are.
yes, they do carry disease. a park ranger contracted Plague from a sick cougar last year and died within 3 days. Plague, Hantavirus, not fun, and the mice may carry it too!
a cheaper alternative is a plastic 1 gallon paint can. sherwin williams was leading the drive to package all of their products in these plastic paint cans, and the lids fit nicely, i personally believe a mouse/squirrel/bird could not get the lid off. $4Aug 12, 2009 at 9:11 am #1520304Brian LewisMember

From the reports here, an Outsak seems like a good idea. I live in the PNW, and normally use an Ursack but didn't even think about bringing it when I went to the Grand Canyon in March.
My experience in hiking through SoCal last year was that there wasn't much likely to bother food if I just slept with it close to me, and — certainly a very limited experience but — that worked fine for me in the Grand Canyon this spring. I did have a ring tail jump up on me in the wee hours of one morning (cowboy camping), but nothing got my food.Aug 12, 2009 at 9:14 am #1520306
yea I agree with Brian, when I did the GC we just slept with our food and had no issues. Only limitation is you can't set up camp and then wander far from camp.Aug 12, 2009 at 9:33 am #1520314Greg MihalikBPL Member
Last November in the GC the food sack inside the RatSak got nibbled/perforated wherever it was against the mesh. It was in the tent vestibule. Meanwhile some other enterprising critter chewed it's way into the tent to reach empty candy bar wrappers, and to eat half of a nosepad on my glasses, as well as sample the crud on my bitevalve.
It is highly dependent on where you choose to camp. If you're at a typical campsite with well-trained critters IMO your food will get chewed – regardless of proximity to you – unless it is somehow protected.Aug 12, 2009 at 11:26 am #1520333Charles GrierBPL Member

My experience has been the same as Greg's; protect your food. This is especially true in the more frequented camp areas. In my experience, Monument, Hermit Camp and Cottonwood are bad for little, toothy, aggressive critters; I've heard the same for Indian Gardens as well. In other, less-used, places such as Boucher Camp or in most of the "At Large" camping areas, the critters are less inclined to associate people with food and you don't need all of the precautions. But, ravens get around a lot more and you need to keep your food protected from them wherever you are.
I use one of the original grey/green Ursacks and so far have had no problems with it in the Grand Canyon. I do hang the sack though.Aug 13, 2009 at 4:00 pm #1520669
From what I understand, no mesh bag is raven proof. I would also have a hard time trusting any fabric to prevent the beak of a raven from entering.
At least they are known for using zippers on backpacks.
I also would be leary of any product claiming "proof" against any animal. Give animals enough time, and they can do some damage.
You can't leave any of them exposed during the day time. Ratsacks can be penetrated by a raven.
Outsak has videos on youtube mentioning ways to keep the ravens away.
food for thought. I'm an Outsak believer. Not sure what generation bag I have-used the one I bought at the canyon.
What I do know, is you have to use something. I wouldn't trust anything plastic against grand canyon rodents.Aug 13, 2009 at 4:21 pm #1520676
the plastic paint cans are fairly durable, that is to say i highly doubt a mouse or squirrel can chew into it given even several hours' time. For one, the can is shaped so that only the bottom edge is small enough for a mouse mouth. and that area is at least 3mm thick, pro'lly as reinforcement.
they are used to package paint. if dropped from waist high, full of paint, they will not open. (dont ask, but i found this out, and was satisfied with the great results)
the container i have uses two compression fitted edges that must both be squeezed together before the lid can come off, not like those old style "screwdriver" removable lids. Of course, they are also much more odorproof than a mesh sack, nearly the same volume and nearly the same weight. I can hold 3-4 days food inside.

I live in Flagstaff and hike in GC all the time. I have never used an ursack. There are basically two critters that are bothersome: Mice, and ravens.
Mice are usually just a problem at night. They aren't nearly as clever as "shelter mice" and are easily foiled by a good hang job. I sleep near my food at night, but keep it out of my tent since mice will sometimes chew through anything they smell food on.
Ravens are an issue during the day and can open zippers and draw cords, etc. They are very intelligent and will have a go at anything they think might contain food- Backpack, stuff sacks, whatever. I try to never leave food unattended during the day in GC.Sep 17, 2009 at 1:28 pm #1528373Tony BonaviaMember
te-wa mentioned the GrubPack. I can vouch for it. It's like the old Ratsack. Cost less than other options I've seen. It's another stainless steel mesh bag. I've had no probs with it. Not sure if they are in stores. I bought mine on-line. http://www.grubpack.com

If you travel to Grand Canyon you must use something if you are planning on camping in a designated camp. The Bright Angel and North Kaibab have ammo cans. Other than that, any designated site has nothing to store food. You need an Outsak, thats why they sell them at Grand Canyon.
If you are traveling in the backcountry, in areas where you get to choose where you will sleep, then the chances of getting raided are diminished. The established camps have resident critters that now an opportunity when they see one. If you are not protecting your food with an Outsak, while in an established camp site, you are risking going hungry for the duration of your trip. Nithing sucks more than rationing food, except rationing water.
Besides, the rodents are infested with disease, and you need to take precautions.Sep 17, 2009 at 1:39 pm #1528377
The Grub pak isn't available in stores. Only online. Good Luck with that.
I will order online, if its available in a store anywhere. I just like to see a retailer decide its a worthy piece of gear. They are usually buying more than one.Sep 17, 2009 at 1:45 pm #1528381
if you need a mesh bag and anything else under the sun realted to hiking, find it at the link above. This is my favorite online shop-I only wish I lived in Tucson so I could wander this store.Sep 17, 2009 at 2:35 pm #1528395
man, summit hut is a great store (2 of 'em). hiking shack in phx is another one.
Dave Baker from summit hut will get anything you want, and hiking shack is same. if you want a wm bag with overfill, they will get it. if you want a event parka nobodys got in stock, they will get it.
also, this thread reminded me of an idea i had, to use a mini-funnel like you would use on a fuel candle or for filling a flask, upside down on the bag line held by a knot. mice trying to shimmy down the string would have a hard time getting around the funnel.
