A: Can putting nails in trees cause longterm health problems for the tree? Trees can be remarkably resilient. As explained by Davey, a tree care company: Healthy trees are tough, and when they’re drilled with a nail or screw, they’ll start a process called compartmentalization, which means they naturally heal the area around the wound and protect the rest ...

A: Trail marking material that will last a few years If you want the quickest way to mark a trail, you could go for forestry marking paint. Some brands will advertize around 5 years of permanence. It requires careful placement of your marks so they are visible along the trail but this is true for any type of marker anyway. The advantages are: No need... (more) |

A: What are these grayish plants with little white "hair" in Joshua Tree National Park? Your description of white hair suggests something like dead Old Man Cactus (Cephalocereus senilis) individuals, or something of the same genus, Cephalocereus. I don't know how abnormal this location would be in southern California. It is said to thrive in hardiness zones 9b to 11 in the US so it migh... (more) |

A: What kind of Rope for a Bosun's Chair Look for any type of line that is meant for running rigging on a sailboat. These lines are made to work with pulleys or block and tackle systems, they have very good strength with more than adequate working load limits, and they can withstand the weather for quite a while. The main idea is to have a ... (more) |

A: How to split 3-5 people into rope teams for glacier travel? I went ahead and fished out my copy of Mountaineering: The Freedom of the Hills, which happens to be the 50th anniversary 8th edition. The reason there isn't much detail in the list you quote is that it's in the primer chapter. In chapter 17, Glacier travel and crevasse rescue (p.375), you have to g... (more) |

A: How can I reduce the pressure of backpack straps on my collarbone, perhaps by fixing padding to the strap? To accomodate the shoulder straps sliding over the collar bone without displacing the padding, I'd build a sleeve of some kind. Especially biking, the straps will want to move around if you go in and out of the saddle. Just to try it out, you could make it entirely of Duct Tape which would make for ... (more) |

A: What’s the main appeal for climbing outdoors? There is a simple explanation that transcends the idea of rock climbing for the sake of it: Some people have other motivations that require rock climbing as a skill, for example peakbaggers. If you need a certain level of proficiency to reach the top of a mountain - let's say climb a 5.8 crux in the... (more) |

A: As of 2019, why do mountaineering courses still teach how to use a paper map? I'll answer both as a geomatician who makes maps (both paper and digital) and deals with GIS data for a living. I'm also a mountaineer, trail runner, backcountry skiier, and outdoorsman with extensive experience both of GNSS receivers and paper maps. Reading skills First off, reading maps is a skil... (more) |

A: How warm should a down jacket be in a layering system? First of all, you shouldn't consider wearing a down jacket under a mostly non-breathable shell. Down loses most of its insulating properties when damp or wet and, assuming strenuous hiking, having it inside your perspiration saturated outer shell will only degrade its performance over the course of y...

A: Is sleeping on the ground in cold weather better than on an air mattress? Effectively, it isn't much better to sleep on an air mattress that isn't specifically made to insulate from the ground than on the ground itself although it does make a slight difference. The main takeaway is that you should always avoid sleeping directly on the ground so even a poorly insulated air... (more) |

A: Fact or Fiction: "If you want to keep your feet warm, wear a hat." (and the various explanations for it) I'm trying to answer in a more empirical way than through scholarly articles but I think it's a good method to prove it to yourselves that wearing a hat does affect other body parts. While there is a common agreement that your head isn't particularly special in terms of its ability to lose heat comp... (more) |

A: First Time Skiing - Only my feet were freezing Try thinner socks. If you're too tight in the boots, you'll be cold. It seems counter intuitive but blood circulation is what keeps you warm, just like what @Fenophter wrote in the comments. An aerobic activity like cross-country skiing gets your blood circulating pretty wildly and you'll be surprise... (more) |

A: Is a slackline, ratchet, and tree protector alone enough equipment to setup the slackline? To the question Is a slackline, ratchet, and tree protector alone enough equipment to setup the slackline? The answer is yes, provided the kit is built for that purpose. In actuality, you could set it up without bark protectors, but that's frowned upon as it will hurt trees (some more than oth... (more) |

A: Is there any evidence that the small canisters (10 liters) of 95% oxygen actually help with altitude sickness? TL;DR summary: There is no evidence that these particular products help with acute mountain sickness. It's difficult to answer the question because the manufacturer for the linked product makes absolutely no claim to the effect that their product helps with altitude sickness. The only direct prais...

A: GSI and similar plastic camping cookware: safe to use over fires? While I worked in outdoors retail, I saw the evolution of GSI's line. The Bugaboo had at some point a very bad but well-known flaw where the plastic lids (polycarbonate then some other molecule when BPA was banned from cooking apparatus) would actually melt. It wasn't a rare occurence, we'd get a few... (more) |

A: Does an ice chest packed full of frozen food need ice? The short answer is that you need to get rid of all the air from inside your ice box. So no, frozen food by themselves won't work. The easiest way to deal with this is to let an outfitter prepare the food. Even for a private unguided trip, you can get outfitters to do all the logistics work from put-... (more) |

A: Can butane be transferred from one pierceable canister to another when its below the boiling point of butane? No. There is a safety system in the newer C206 canisters that should prevent you from emptying a pierced can, unintentionally or not. It remains to be found if this works at low temperature and pressures though. However, the C206 GLS cartridge has a new integrated flow reducing system, the Gas Lo... (more) |

A: Boots: Does light damage affect waterproofing? No. If the boots have a Gore-Tex membrane, this is a PTFE film that is sandwiched between the inner lining and the upper. Light going through a glass pane is mostly harmless. For example, most of the UV light (UVB) is blocked by glass. The only issue a pair of boots left in a display might have is co... (more) |

A: What is this square plastic thing with small black flat glass marbles in the Uintas? Without having more info on the specific parameters of the study, it's hard to know exactly what they were looking for. Either water or snowpack characterization might be very likely subjects.

A: What type of lizard is this grey and orange one I found near the Grand Canyon? That's definitely a desert horned lizard although I'm not expert enough to identify the sub-species.

A: What type of insect is this orange-camouflaged creature? That is a species of longhorn beetle called Aristobia approximator. There are two or three different species that live in my region but I wasn't familiar with this particular one which is quite impressive looking. Since it seems to feed on teak, this has to be an Asian species. (more) |

A: Skis versus snow shoes - when to choose which for travelling the backcountry? First off, I want to make clear that this applies to skiing and snowshoeing as a means of long-distance travel. It doesn't directly apply to skiing in specifically for the descents. Skis are better for: Lake traveling: The snow on frozen lakes tends to be firmer and this enables the ski's inheren... (more) |

A: Garmin Fenix 3 - Temperature spikes result in abnormal elevation changes I would expect an aneroid or electronic barometer to do exactly that.

A: What basic body position should I be in during a downhill ski run? From what you describe as being taught, the basic position seems to align with the concept of being relaxed and in an active stance as opposed to being stiff and static. This makes it so you can respond to changes like bumps and ridges more adquately and in turn retain more control than if you were b... (more) |

A: Can you "kick and glide" and climb without skins in Alpine Touring ski gear? I haven't tried it myself, but I know of someone who sometimes waxes the entire base of his AT skis with grip wax instead of putting his skins on. It works perfectly fine for exactly the same conditions that would work with cross-country skis, so a gentle uphill will work. His first descent might be ... (more) |

A: Keeping water from freezing while cross country skiing With a hydration pouch, if body heat keeps the reservoir ice-free, the best option is to simply blow into the tube so water retreats into the reservoir after each sip.

A: What counts as climbing a mountain? As a peakbagger, I often have that sort of conversation. First you need to define your terms. What constitutes a mountain, a summit, a high point - all those matter. I have "climbed" high points in farm fields that are on such flat areas that we can't even know for certain where it's actually highest... (more) |

A: What gear should I carry along for winter emergencies? The safest concept is to always plan for the worst case. Of course, best practice varies according to context.

Of course the photo... (more) |

A: is it safe to use a 4mm cord for French Prusik auto-block friction hitch when rappelling off parallel 10mm dynamic rope? I would say no. 4mm is just too small. That's really accessory cord at that point. Considering it's only about the ability of the cord to constrict on the rope and block, the diameter is always a tradeoff between having lots of grabbing power and being easier to loosen after having been loaded. The... (more) |

A: Down is escaping my jacket, especially over a wool sweater Down will inevitably pierce through thin fabrics (an thicker ones too, just less frequently). It's in the nature of quills to do so and even if very fine, there are quills nonetheless. The lighter the denier of the fabric or the looser it's woven, the easier the down will get through.

A: What is head/lift indication in a digital compass on a sailboat? When going upwind, a header is when there is a wind shift towards your bow, which would make you deviate further from your original heading provided you don't adjust trim. A lift is the opposite.

A: Would a lightweight 2-person tent or medium weight 3-person tent be better for near freezing weather? In my experience, different tents aren't incredibly warmer than others.

Your last paragraph, which is how you're basing your choice, makes two questionable assumptions: It's a ... (more) |

A: Can I use a trail camera to identify a roadside litterer? I personally would rather just set an action camera to record over the timespan the litterer usually comes by.
