The city would retain ownership wherever it goes. |

The Ely greenstone (as the sign in the photo suggests) is an an ancient basaltic lava flow (think Hawaii). The "pillows" are the result of this lava being erupted and flowing underwater. The outer surfaces cool quickly and the inside remains liquid longer and forms these blocky tubes we call pillows. The green color is the result of metamorphism, that is, alteration due to high temperature, pressure, and fluids in the crust. The greenish color comes from the transformation of minerals in the basalt to common green minerals like chlorite, actinolite, and epidote. As a geologist, my opinion is that the issue with moving outcrops such as this are twofold. One, you risk damaging the rock. Two, you lose geological context. Sites such as these can be great resources for teaching and future research. However, if you move it you risk losing that for future generations. This is especially true for Magnetic Rock. Then again, if Pillow Rock was put there by a mine then thats less of an issue. |

Looking at the pictures, it seems large to have been moved by a mine. If I was just trying to get it out of the way, it would be in smaller pieces. I wouldn't be surprised if it is a glacial erratic, albeit not from very far away. I'm also an earth scientist (seismology) and understand the research issues but also see a lot of educational value in getting it somewhere it gets seen more. |

It would be a more central location on Sheridan street than at the NABC. |

is this another stimulus plan to put people to work? |

According to Dick Ojakangas, Professor Emeritus of Geology UMD (and husband of Bea), the Pillow Rock is indeed a glacial erratic that originated about 100 meters to the north of where it is now located. How large it is though, he never said. |

quote Zulu: "There was some talk of moving it to the parking lot on Chapman Street where Pamida used to be. Did anyone considered moving it to that parking lot East of Mike's Liquors? Yes Patrick, some did suggest moving it to the parking lot just east of Mike's Liquor, but they have gone missing, and no one has mentioned it since!! :) |

Yeah, Ely isn't big but sometimes you need to make it easy on people if you want to educate them. |

Geology rocks, please pardon the expression. |

quote scat: "...If it's that special, put it in the bear thingy. That seems to make sense. An exhibit type environment where it's story could be told and seen." and, move Kawishiwi Falls to Whiteside Park while you're at it. Lots closer and you avoid that annoying walk in the woods. |

Why move it at all? Is some real estate speculator angling to purchase the property for development? TGO, what's the "Rest of the Story?" |

They would then build a Kiosk, so people could drink coffee and chat when mingling at "The Rock!". The idea then went to the Bear Center, for whatever reason. I think it's ridiculous since it will probably shatter when the attempt to move it begins. And just to play Devil's Advocate and be a pain in the a**, I want an EIS to see the amount of sulfides that would be spread around in the process, just as some want for the highway rebuild near Eagles Nest on highway 169. Let "Sulfide Rock" stay right where it is, and anyone who really wants to see it can walk over as others have suggested!! However, I think moving the Dairy Queen to the Fall Lake Landing, does have some merit!! :) |

quote The Great Outdoors: "Some couple came up with the idea to move it to Chapman Street, in the vacant lot between the old James Drug Store and the old Pamida Shop. Agree. It is where it is for a reason; leave it there! Not that hard to go check it out-and it is worth the short side trip. |

It has green "pillows" of Ely greenstone embedded in it. I took a CE geology class at VCC a few years ago and we studied it. I seem to recall the pillows are green because they formed underwater and algae colored them. They believe the pillows did not form in the attitude the rock sits now by studying how they look. Nobody knows if a glacier placed it where it is now or because it's near the edge of a mine it was put there to get it out of the way. They also don't know how deep it goes and if it's like a tooth with deep roots. As I understand it The North American Bear Center wants it located there and they will finance the move. I wonder what type of equipment it would require to move it and if it can be done without damaging it? If it was up to me and I could afford it I would move it the where the Pioneer Mine Headframe and museum is. The area is open for tours and has some great historical pieces and interpretative displays. The Ely city council voted last evening to get public input before making a decision. You can Google it to see photos and read about the move first proposed in 2014. If the public is in favor of a move maybe Magnetic Rock could be moved closer to the Gunflint Trail to avoid the long unshaded walk to see it. |

What do you mean by: "If the public is in favor of a move maybe Magnetic Rock could be moved closer to the Gunflint Trail to avoid the long unshaded walk to see it." It would be a shame if it wasn't structurally sound and it broke apart when they tried to move it. Then again - we didn't stay too long since I felt awkward in the neighborhood. I do like the idea of a private organization financing the move vs. public dollars. |

My magnetic rock comment was meant to be a joke although it may get people thinking. |

The key would be figuring out how far down it goes. Some small drill holes around the edges, to see when it gets hit again might help and be simple. A geophysics class could also do some gravity and magnetic studies to try and figure it out. While having the bear center fund any work sounds good, I like the idea of the Pioneer Mine or somewhere on Sheridan Street where it is seen more. |

Oh schist. Good luck with that Ely. |

I think while they're at it they should move the D.Q. out to Fall Lake campground too. |
