This answer applies only to signal mirrors which are two-sided and have an aiming hole in the middle, which should be the case with any good signal mirror. My answer will partially duplicate a pri...
It's similar to sea foam; nothing to worry about. This usually results from the build up of broken down organic matter that has dissolved in the water and foamed up due to turbulence (i.e. wind/wav...
Using the Way back machine for http://www.icebreaker.com/en/black_sheep (which used to exist, but search engines still link to) it said: The ultimate in luxury, soft merino wool clothing, the I...
With a tent you would have protection from wind chill and unless you can cut the air flow to your skin some other way, the added effect of wind chill depends on the wind speed. The forumla is: wi...
After waiting months for the leaves to return on the tree and reading the comment made by Jamesqf, this is a Honey Locust Tree. On the Wikipedia page for the tree, there is a picture that matches ...
It depends. Maybe colder, maybe not. (Yeah, right.) Anyway, two major rules for hammock happiness: (1) Sleeping pads don't work. (2) You must arrange your rain fly to block air flow. Sleeping p...
A modern (Korean War era and later, at least) signal mirror has a hole in the center, and the hole is surrounded by a grid of retroreflectors. You aim the mirror spot at something close by, then lo...
I used to have a marine (reef) aquarium. One part of filtration is called a foam fractionator. By blowing fine bubbles in a thin column, you produce a great deal of surface area where air and wat...
It looks a lot like there's a power station just downstream (photo), which can be seen on openstreetmap. I suspect that the power plant is being used to respond to peak loads for which hydro is ve...
Get all the water out from the beginning. Then unscrew the dumpvalves and connect the BCD with the low pressure inflator hose to a tank. Inflate the BCD. The BCD won't inflate as the air is getting...
At least in the US forecast models do change. In unsettled air they change faster. Two possiblies come to mind for why this line would "disappear" or move to another day. Both are kind of related. ...
It is very close to a 12 hour day of light every day in the Southern Philippines. The mountains behind were I live have some effect on shorter afternoon. & the sun rises over the S Pacific. We ...
If you neglect the influence of the terrain/buildings, the atmosphere and the height above sea level, both the time with and without sunlight is very close to 12 hours on the equator (other minor d...
Are there any other more peaceful routes to the castle? Yes, there is another trail called Jugendstrasse. It leads towards the Alpsee lake, around to Mary's bridge and eventually back to Neusc...
Water proof spray would only help with the outside of the bag. Waterproofing is available that the bag is washed in which coats all the down with hydrophobic water repellant. Or ready made ones ar...
Imagine for a minute that the Earth is perfectly spherical, that sunlight arrives "from infinity", and that any given spot is either lit or unlit. Then, at any given time, exactly half the surface...
What you need is a screw extractor. Usually they are sold with reverse threaded drill bits. You drill into the screw that is recessed and then stick an object in that hole like a flat bladed screw...
You can't. All you can do is throughly inspect yourself or have someone check you over to see if they can find any. But there's nothing you can do to ensure there aren't anymore around, you can on...
I have drank it. These were the big vines that grew to the top of trees. Just cut them & let the water flow into a collector below. Wild grapes here not domestic. I had no ill effects from thi...
Not exactly grape sap, but a local merchant to me is selling what he calls Organic Water. The source is the liquid evaporated off during the Maple Syrup manufacturing process. Because the source is...
If you want to make Coghlan's you can get the ingredients from the MSDS. But that seems kind of extreme. "Make our own camp soap" is not very clear.
What I use for dish washing is Ecover ZERO Dish Soap. It's made with plant-based and mineral ingredients which makes it biodegradable. Comes in a 25oz bottle so it should be enough for you for refi...
I'm not sure about grape sap but I can tell you that birch sap is great and has no ill effects. You can collect it quickly and easily in the break of winter/early spring and it contains heterosides...
There's one piece of equipment I've carried with me on every trip, even on day trips and that's a lightweight and durable rescue blanket. Not only can it help you to stay warm (shiny side in) but i...
Sauna. And not that joke-of-a-sauna but a real Scandinavian sauna with 80°C / 176°F. One thing with ticks is that they can take an enormous amount of beating and other forms of killing attempts but...
