Depends on how much you put on. It may be helpful to first identify why you are a mosquito magnet. Mosquitos are attracted to primarily two things that you can control: odour and heat. Unfortunate...
Aspect ratio describes the ratio between sail/keel height divided by (average) width. So a high aspect ratio is tall and skinny and a low aspect ratio is short and fat. For sails one of the main a...
Addition to ShemSeger's answer, from way back in my mind: A concave spot in the ice is stronger than a convex spot, given equal ice quality. The ice should be deeper than the screw is long, so th...
This is not an easy question to answer. More lumens means better light, normally also further range. But if you dive in areas with lots of suspended particles in the water you will get a lot of bac...
Garmin Basecamp is a free application that allows people to share tracks for various activities. I have found a ton of trails this way. http://adventures.garmin.com/
Yes, you can use dynamically soaring as one variable in attempting identification, in addition to size, wing, body, beak, feet, etc. (all the usual ways of narrowing down your bird). But you can't ...
I haven't tried this personally but I would imagine that waterproof/resistant paper used for printing out maps would work well due the slightly plastic feel. A quick search using your favorite sea...
Basically people look at the frostbites in 4 principle stages. First Degree Frostbite - Frostnip: Fingers/toes/nose feel very cold, prolonged exposure would numb them. This isn't deep in your bod...
This is really just a hypothesis, but here in the UK we also get mixed wader flocks. A significant reason for large/mixed flocks to occur is predation. Watch out for what happens when a large flock...
First I will describe the stages of frostbite focusing on how to detect them and what are the implications of each. Secondly I will address handling frostbite. Classification Stages of frostbite ...
Layers are useful, but I've found upper body layering more critical (and easier to alter- you don't need to take your boots off). For me, the question is how much wind will there be, and how active...
"hanging out" together happens because different species eat the same food, require the same nesting areas, migrate in the same flyways, etc. Many species compete/become territorial for nesting are...
Keels on boats are designed to offset the push of the wind on the sails by transferring the lateral force into a forward motion. The boat can't go sideways because of the keel, so it goes forward. ...
I personally use a base layer (which also retains heat even when wet) with the same quick-dry pants that I use for my summer hiking. I treat these pants occasionally with a water-repellant spray an...
I suggest that this is because you climb in gyms more than you do outside. Back when gyms were rare, when I went to the gym, it felt way harder for the grade than outside routes. That was because...
The suggestion to use wasp spray for defense seems to be common enough that there’s a Snopes page on the topic. This particular urban legend is more often brought up in the context of defense agai...
The answer is yes. But not for everyone. The first two people on record to die on Everest were George Mallory and Andrew Irvine. There's speculation that they may have even summited the Mountain, ...
You already identified some key points in your question. Speaking from study, mentoring and experience, here's my answer. Plenty of fallen branches. Not the softest to sleep directly on however, ...
It depends. A simple fact: You conduct HEAT. You do not conduct COLD. Wrap your head around that. 2nd Simple Fact: Water conducts HEAT more efficiently than air. Now, if you're trying to chil...
There can be a slight weight savings for a double bag over two single bags. This is difficult to fully calculate, especially if one person sleeps warmer than the other or if there is a height diffe...
It's traditional to construct a bed of evergreen tree boughs in survival situations (fir or cedar are the best kind), I've done it a number of times on private land, and deep in the wilderness on c...
When free climbing with a partner the first time, I explain that he/she owes me a beer for every nut that I need the nut tool for. This drastically improves efficiency since it makes the leader rea...
In terms of clothing insulation there is the concept of the CLO. The key equation is T = (31 − 0.155·P·R)°C where P is 48 W/m² while sleeping, R is the number of CLOs, and T is the temperature in...
On designated trails that are infrequently traveled and maintained, using them to mark a faint or overgrown section of trail, the point a trail passes under a large downed tree, a switchback, a tra...
A kisser button, perhaps? They are a button on your string designed specifically to help orient your head.
