OpenStreetMap wiki describes a technique called aimed straight segments. You need a GPS device or app that can record a trace and show it on the map. Start from a location where you can see the ...
Pine Martens aren't native to the Lake District as yet - you need to go further north to find them (and then in small numbers). This will most likely be one the more common mustelids - Stoats will...
TLDR: It has happened once to a dog and it is possible that it could happen to birds but I can find no instances of it happening. In rare cases, skunk spray can have more effects than just smell o...
Since you and I belong to the same geography for trekking/hiking, I think I can add 2 cents to this. I typically follow a similar pattern from what Charlie answered above. I typically avoid going ...
A bell curve simply measures your median level of climbing ability in your gym. The "science" behind it is simply to cater to your customers, you need to set routes to attract the biggest demograph...
Another answer describes a good method for triangulating a position from two or more viewpoints. This is a method you could use if you have only one viewpoint, but also have access to a topographi...
If you're in Britain, you can either provide GPS coordinates in latitude and longitude as normal, or an Ordnance Survey grid reference which is easily obtained from the maps normally used in Britai...
Although the question specified using no equipment beyond a standard mobile phone, I think it's worth pointing out that VHF and UHF radio signals can typically be heard over greater distances than ...
I use Barbour wax on the bottom half of my sleeping bag, bivvi bag and fabsil gold on my tent outer and both on most clothing, Depending on what you want to water proof always test first.i always r...
New Zealand has many tracks with river crossings, and it is known that rivers can be deadly if approached without respect. With that in mind, always check out what is down stream for if things go p...
The fine answer of @Monster is correct for UVB rays, but the point raised by @imsodin is pertinent. The following information and quotes are taken from the Skin Cancer Foundation, UVA and UVB. Wh...
Purely theoretical (in practice sunscreen isn't as strong as it says on the bottle to begin with) you multiply it. If 1/3rd of the UV photons make it through the first layer, and of those that mad...
Quick synopsis: Beetles infested tree. See circular holes. Woodpeckers made larger holes to get at the beetles. Tree died. Bark fell off, helped along by animals trying to get to the tasty bee...
It sounds like you need your very own wetsuit, preferably one that is made for cold waters. Not sure if you can be too warm in a wetsuit, honestly, I am not an expert in this, but you definitely ne...
As an answer that will be of immediate use without investing a lot of money: You can wear two wetsuits, one over the other. I have done this in the past when the rental place couldn't provide a wa...
I am the lead hardware engineer for Backcountry Access. Interference from personal electronic devices (PED) is very real, and it can range anywhere from minimal impact to severe. The reasons are ...
All of the answers above are great but I would like to add about the rubber wear. If you do commit to buying used climbing shoes, take note of the rubber wear. If the toes are worn unevenly or you ...
(Started as comment but then I realized it's getting too long). Short version: quite in contrast to Monster's advise, I recommend to start with a splitting maul if possible, because the splitting ...
The answer is yes, there are bubble free compasses. It seems that the trick to getting a compass to not have bubbles is to use a thermo-elastic capsule which flexes with the temperature changes. ...
I thought I would weigh in with the other method you mentioned. Drysuits. You would need to take a course to use it safely, there is more to it than diving in a wetsuit. As someone who primarily di...
Because the characteristic of a backpack in question is volume or how much content it can hold, not mass. An extreme example: If I fill lead into a 20l pack, I get ~225kg, if I fill styropor into a...
When travelling on extremely remote roads, you need to prepare for the worst. This is even more true if you are travelling in a climate where the weather might kill you within days, such as in ext...
I started to feed these smart cautious birds a few years ago in my back yard in the winter. In my amazement they are also guardian birds for morning doves. I had watched these crows chase and inter...
I have always learned that when you go to remote areas you should have at least a basic knowledge of car repair and depending on the make of car and the area you go to your knowledge should be good...
