I got out this week to run two guys up into the hills of Minas Gerais for some mountain survival practice. The mountains here run up to a little over 6000 feet in my area. In the winter it will get down below freezing, but even in the summer the temps get down to about 50 on top and there is usually dense fog, high wind, and driving rain. There is also very little if anything to burn up there (what is there is soaking wet) so it isn’t a place you want to stay overnight.

Renato - I had them cut poles in a small forest in the valley as they are hard to come by up top. Straight poles are a great aid to making shelters up there.

Valcione - These packs look large but they are basically empty. They are only carrying about 15 lbs of gear on the trip.

Since this was the first time for both of these guys up in the higher elevations (Renato’s first time in the bush ever). I had decided to have them camp together under a large rock overhang, halfway to the top, that I have used many times before. We got there and the wind direction was such tat it wasn’t as protected as we were hoping. Since the second night we were going to make individual shelters anyway we decided to spread out and find our own locations

I knew of a cave nearby where I had sheltered from a storm before but had never considered sleeping there. I headed over there to see if it was adaptable. I needed something quick as I had to spend time talking them both through setting up their shelters. The cave had a nice flat section in the front. I tested the ground with my machete. It was made of dirt interspersed with large flat flakes that had come off the ceiling but was large enough to sleep one, six foot, American. I sent them off to scout out locations and see what they could come up with as I quick dug out the floor to level and determined that I could come back and set myself up without too much trouble.

Prepping the cave floor, I used a 12 inch Tramontina. Did it dull the edge? Yes, but that’s what the Ez-Lap is for.

Valcione had found a huge rock overhang about 50 meters away and uphill with a small body-shaped cleft in the rocks. The mountain had burned last year and the cleft was filled with dry ashes, a very good sign in rainy season. On a sloping shelf above his sleeping area there was a large rock resting there. This thing was a widow-maker for sure. I gave it a tug and it came down right where his head was going to spend the night. He set about chopping and digging to adapt that space.

I found Renato still searching for a spot and led him to a place I had found last year and had planned to use myself this trip. It had a long rock wall with another rock that formed a ”L” and was a very good windbreak. The flat spot in front of it could be covered over with a poncho and a contractor bag or two to make a very good shelter given the prevailing winds.


For shelter resources they each had a bivy sack, tropical bag, cordage, and a poncho as well as a 55 gallon contractor bag as a reserve. This is the minimum I recommend for a day hike up in the hills here. For bedding they had to make a mattress of grass.

More to come...
 
I showed Renato how to dig out a flat space and level it out for sleeping and indicated the kind of grass, plants, and moss he could use to make his bed.

I got back to Valcione’s spot, dubbed the “Hyena’s Lair” (due to his nickname) and helped him rig his poncho to best take advantage of the space. Checking back with Renato he was well on his way to making the space livable so I headed back to my cave.

The wind was a steady 6mph from the NNW. The cave is formed under a large slab that at one point let loose from above and slid downhill to become wedged against another boulder. The support boulder divided the cave into two sections with a jumble of rock in the middle. The wind was hitting the far side and whipping through the center of the cave like a wind tunnel. I didn’t have time to deal with this, or look for another spot, so I went out to rip up a few armloads of grass for a floor. I was “cheating” in that I brought along a ¾ length Thermarest pad for myself. Sleeping on grass is fine but only if you have enough time to gather it and I didn’t know if I would have time for that after setting them up.

About sundown I had myself situated and went out to check on the guys. They were both enthusiastic about their shelters; they each had plenty of water and alcohol for their stoves. It was dinnertime for me, Ramen noodles. The sun went down and the wind picked up. I was really starting to be bothered by the wind in my cave. Outside it was about 6 mph, inside it was more like 10 – 15. I didn’t have to blow on my food, just hold it up.

Part of this adventure was for the guys to experience a night solo on the mountain. We were strung out in a triangle with about 75 meters between them and me downhill in the center. They each had their whistles in case something really went wrong. There was a 90% chance of rain and I was tired, it was time for them to fend for themselves.

The weather report was correct; we got pounded with rain all night. The wind was sweeping the rain away from my rock overhang but at the back end of the cave it was forcing through the center and carrying spray with it. I really regretted not making up some form of windbreak. I did think of stringing up my poncho in the center of the cave but decided not to as it would be needed if I had to take care of either of the guys in the event of a shelter emergency. My bivy took care of the wind/spray problem and I slept well.

More to come…

Great pics. looks like a fun adventure and learning experience. That cave shelter is too cool, I love rock caves like that.
 
nice looking trip, bummer about the cave...but i guess that's what the bivy bag is for right?

good on you for sharing your knowledge
 
Mac, that reminds me of the rock cave camping I used to do out in AZ. Nice pics and post Mac. Looks like a great place to go out camping.
 
The scond night I did rig up the poncho to divide the cave in half. This greatly reduced the wind in my sleeping area.

I can't strees enough how much getting out of the wind makes a difference, especially if you are wet. Rock shelters can be tricky in windy areas, some of them will block the wind entirely but then if it shifts direction they can force the wind though a narrow channel and make it harder.

The second night we got hit with hard rain and high winds all night. My bivy got soaked from the knees down with spray blowing around the opening at my feet but the bag inside stayed dry.

A bivy is well worth the investment. Mac
 
Nice story/picture documentation and shelter great tips!! Thanks! It is these little documentaries that provide so much information and memory learning for our own training experiences. Great job!
 
Very interesting looking area. Not the type of terrain that I normally associate with Brazil.

I'm really interested in Geology, so I would love to visit the Minas Gerais region simply to look at rocks. There are a lot of mineral specimens sold in the US that come from that region.
 
Thanks for the positive feedback on this trip. I get a kick out of seeing guys discover the freedom of the bush for the first time. I know lot of people who post here are involved in scouts and other "introductory activities". I would encourage anyone who is really interested in wilderness survival to get active in passing it on. The quickest paths to learning are teaching and the personal experience of actually doing it "for real".

On this trip we had planned to spend our second night on top of the mountain but conditions were bad enough that we had to use the same area to camp for both nights. Part of wildeness survival training is knowing how not to put yourself into a risky situation. At the same time you have to introduce enough stress into the situation to make it a true learning experience. I think I've failed them if at some point they don't stop and think "What am I doing here?" Both of them "got there" on this trip.

I think we struck a pretty good balance with this experience. They did this with the minimum recommended equipment and a daily food ration of 1 ramen, two instant oatmeal packets, coffee, about what you could include in a daypack and not be encumbered.

Aside from my thermarest pad and the tropical bags (admittedly luxury items) all of the "gear bubble" they carried was essential and would have fit in a daypack and their pockets.

The kit list consisted of...

Shelter- Bivy, poncho, contactor bag, cordage, tropical bag
Fire - Bic, Doan tool, BSA Hotspark, PJ cotton tinder
Water - US Army canteen/cup/stove sleeve, 2 liter Platypus bag, Chlorine tabs, 2% iodine, PVC water filter, 60 ml syringe and tube (not used on this trip as the mountain was soaked)
Signals - Cell phone, signal mirror, AA maglight, whistle
Navigation - Compass, pace counter, small notebook and pen (we have no maps of this area still)
Blades - Machete, Mora SWAK, I also carried my SAK

Their day clothes were BDU's of some form or another, at night they had sweats carried in a drybag. I think it is important to carry a warm, dry set of PJ's. Conditions at this time of year are so variable that you can't count on getting dry before you have to bed down. Brazil can be surprisingly cold at night especially if you go up in the higher elevations or it rains.

After seeing the photos my daughter (16) is bugging me to take her out again. I motivate the guys out there by saying "Buck up, you aren't doing anything my daughter hasn't done for twice as long and with half as much!" That always works.

Lamertiana,

The area we were in is near Ouro Preto, the mineral epicenter of Minas Gerais. We gots rocks if that's what you're into.

Thanks for having a look.
