The Yellowstone Super Volcano More Massive Than Previously Thought

As you all know Yellowstone National Park is actually a gigantic super volcano. The volcano is the whole reason the place formed because without the hot molten rock the water wouldn’t be able to form into steam. What started the debate between the two different ways to measure underground volcano’s either by seismic waves or by electrical conductivity was that some scientists thought it was bigger some thought it was the same as before. When it comes to electrical conductivity scanning “It’s a totally new and different way of looking at the volcanic roots of Yellowstone”, says geophysicist Robert Smith of the University of Utah.

            Scientists have now been able to see much more of the “roots of Yellowstone” and now conclude that there earlier calculations were wrong, turns out that the super volcano is 20 % larger than they once thought to be. The volcano is said to spread over Montana, Wyoming, and Idaho so it’s over 400 miles long. The electrical conductivity scan can only see down about 200 miles underground so they don’t actually know if that’s where it ends or not. So before the electrical conductivity scan was done scientists believed that the volcano was 25 miles by 37 miles wide.  But now they have found out that the plume is about 500 miles long by 400 miles wide and they can’t even see the bottom of it.

Now that there is a new way to see into the volcano scientists believe that they are now able to better understand them and predict when an event may occur. So let’s all just keep our fingers crossed that it doesn’t happen in any of our lifetimes.

Bed Time

                                                                                                           

            Have you ever been camping before but froze when it came time for bed? Chances are you have which is why I’m going to help you choose your next cold weather sleeping bag. Sleeping bags come in many different materials, shapes, sizes, and most importantly the temperature rating. When it comes to winter camping this is of the utmost importance because who wants to freeze when you’re trying to sleep?

            When choosing a sleeping bag for winter camping, you first need to figure out how cold it’s going to be. This is important because all the sleeping bags have their own temperature ratings. The temperature rating is used to show how warm a bag will keep you in a cold climate. An expert from Adventure Sports Online, an informational resource for outdoor enthusiasts, explains, “You should go with a bag rated to at least 10 or 15 degrees lower than the lowest nighttime temperature you will encounter. It is always easier to unzip and cool off than it is to get warm.” Remember, when you’re choosing a winter sleeping bag, get one that fully covers the climate in your area.

            Next on the check list for a winter sleeping bag is the shape and size of it. When choosing a winter sleeping bag there are so many different sizes for them, but did you know that there are two or even three person bags? One of the good factors about these bags is you get body heat from other people so you actually stay warmer. When it comes to the shape you have two choices: the mummy bag which is a snugger fit. This might be a little more uncomfortable because it’s a tight bag, but that keeps the fabric closer to your body so it keeps you warmer. Then there is the regular rectangle bag these are good for the people that want the most room while their sleeping.

            Finally, the last feature about a sleeping bag for winter camping is what the material is made of. Sleeping bags can be made from either goose down, or synthetic material. The good thing about goose down is it is very lightweight and warm. Also another big factor about these two materials is the cost of each, the goose down bags are normally the more expensive ones but you might find one cheaper than a synthetic.

            The sleeping bag is one of the most important things for camping especially when it’s cold outside. So remember whenever you’re camping to have a warm bag to crawl into at night so your trip won’t be a cold one. So start looking for your new cold weather bag, for your next outdoor adventure now.
