Q: I was watching a documentary about pompeii and the eruption in 79 AD but i fell asleep before it ended. The last thing i remember seeing was what looked like rock covered people?how did this happen? im guessing it was due to the pyroclastic flow? but im not 100% sure.: the ash from the volcano like extremely hot dry cement went everywhere when landing on the living it stuck with more coming and burned through skin absorbing the moisture in the blood with capillary action until that body was `dry` the rest kept coming effectively curing the process - this is how i think it may have gone but still looking for the real fact

Q: We have a crimson maple tree in our yard that needs to be moved approx' 50' due to an addition to our home. It is 20' tall with a drip line of 15 feet and a trunk diameter of 6quot; -7quot;. Some landscapers say to move it with a tree spade, and others say it should by hand dug and balled with burlap before moving. Which method would you recommend?: A 20 foot tree is really too big for you to move by yourself. The roots will have spread approx. 20 feet across and they may go that deep as well. That makes for a very major dig in your yard. I would look at having professional landscapers do it. The Muse
