How 1 person can lift 200# food bear bags 20' up

Too many in one group.

To clarify …. 

I’m not sure if the additional weight of pulleys & such is worth it at Philmont.  Also, this rig fails if either rope is cut, unlike the Philmont-way that requires both ropes be cut.

Perhaps…. as poles-n-cables fail, they’ll be replaced one-by-one with food lockers.

Good grief I hope so.  I realize the bear bags teach a skill, but when the camp sites are fixed, bear-proof lockers certainly make a lot more sense.

I believe I read in the guide that pulley systems are not allowed at Philmont.

Yes, lockers are easier and more efficient.  But since when is Philmont about doing what is easy and efficient at the expense of the learning and the experience?

More important than teaching a skill (which is of marginal value outside of a backpacking scenario), bear bags provide a challenge to overcome by working together.  Part of the team building.  Pushing them into the “storming” phase so they can work through it and come out a stronger team and better equipped individuals.

ITEMS PROHIBITED:
• Deodorant
• Radios/MP3 Players/Video Game Devices
• Hammocks
• Turkey Bags
• Bear Bag Pulley Systems

Philmont’s backcountry camps are not fixed. They open and close camps each season according to use and need.

I certainly get the prohibitied items (though I never would have thought you would have to prohibit a Bear Bag Pulley System) but why are Turkey Bags prohibited?  They are too small for me, but I know some people that use them as pack liners in smaller packs (like the Burn).

Turkey bags are prohibited for cooking.  I suppose if you wanted to use one as a pack liner they would not care about that.

Who cares about lifting the 200 pounds, I would be more worried about lowering it.  Sounds like an accident just waiting to happen.  My 2 cents

If you use two people it would be a breeze.  Square rigged sailing ships didn’t have so many block and tackle and they were able to hoist large sails with only a few people. You have to have a reasonable anchor point and something for the line to slide over.  The old ships used a wooden pin or circle for the slide and a belaying pin for the anchor.  Thank you Sea Base!

Pulling a ¼” nylon rope over a 3/8” galvanized steel bear cable creates a lot of friction. Soon after a commissary pick-up you may have 3, 4 or 5 days of food for 12 campers. It usually takes two or three Scouts on each of the two ends of the bear rope with two or three Scouts lifting the bear bags.

A few quick observations:

One Person Lifting:   Given that the Philmont’s bear bag approach is a double haul system,  there will always be at least two persons pulling up a load (one on each line)

Weight Being Lifted:  Based on measuring Philmont surplus food packets, the average weight is in the 2 lb range per person, per day.  Remember, Breakfast, Lunch and Dinner are packaged for servings of two, so the overall weight of the three meal packages are divided by two to get to the per person, per day weight.  (Breakfast & Lunch are typically done as food buddy style, where as the Dinner is done in a big pot per Philmont’s version of the Patrol Method.)

4 days of food per person weighs approximately 8 lbs per person.   The maximum crew size is 12, which in food weight would approximately equal 8 x 12 = 96 lbs of food in total.

Because of the bulk of the food packages, and the volume of the bear bags (grain bags 50 lb size) that Philmont issues, most larger crews have to hang two main bags (not including the Opps Bag).  While that doubles the bear bag hanging effort, it does cut the lift weight in half.

Pulley System:  Back in 2010, Al Geist demonstrated a pulley method to Philmont officials for their approval.   It was not accepted.

Al’s method also saved the wear & tear on the tie off tree.

YMMV,

Enjoy your Trek!

The major short coming of that hook and pulley system is it has no redundancy. Like a chain, it is only as reliable as its weakest link. If any single part fails, or is molested by any animal, the food hits the ground.

And it has multiple parts and requires a special made one-of-a-kind gadget.

Murphy’s Law states, “whatever can go wrong, will go wrong”.

Whereas Philmont’s bear rope system has redundancy. Everything has a backed-up, even the oops rope.

But its real beauty is its simplicity, no special made one-of-a-kind gadget, just a rope. KISS
