StumbleUponScientists Discover Amazing Free Compass for Hikers and Backpackers
Scientists in Europe have made an interesting new discovery which could provide a useful tool for adventurous and outdoorsy types when hoofing about in wilderness areas. While we obviously don’t recommend it to hikers and backpackers in place of a sturdy compass and map - it’s a tip worth storing in the memory bank for emergencies.
It seems incredible that ranchers and farmers have not noticed this new-found phenomenon before. Those familiar with the habits of cows will be aware that they tend to stand with their body side-on to the sun to warm up on cold days and parallel to the wind for least resistance on windy days. I grew up being told that when cows lie down it means rain is on the way, so they can also serve as a makeshift barometer.
Scientists have studied more than 8,500 cattle and close to 3,000 deer in various locations around the world. They found that on days when the weather was fine and calm the animals would align their bodies on the north-south axis of Earth’s magnetic field. Certain deer were also noted to turn their heads to face magnetic north (not geographic north) during resting and grazing. The observation was made using satellite images via Google Earth and other non-obtrusive methods for tracking the animals.
It’s well known that many creatures, such as fish, birds, butterflies and other insects have built-in compasses for navigation on their migration routes. Cows don’t migrate, we hear you say, so why would they need a compass? While we can’t vouch for the accuracy of this report, or the waywardness of cows, it doesn’t appear to be a load of old bull either. We thought it worth passing along for the next time you and your travel companions are lost and can’t find your way home. Instead of chewing the cud and butting heads about directions it might be an idea to stop arguing and go look for a cow. (If you’re really lucky it’ll be a Limousin).
The animals can only do so much to help in an emergency, so don’t forget to take out Travel or Backpacker Insurance for your next adventure.
