7 amazing holes « deputydog

For the next two hours, I read up on the Great Blue Hole, which is completely fascinating, and beautiful, to me. I haven't tried yet, but I would love to see this on google earth.

The sinkhole in Guatemala is amazing as well (100m deep!!). I have no idea how to look for it on Google earth or if it is too new. Has anybody seen this?

I figured it would be fun to post about Earth holes here and see what came from it (the discussion, not the hole ).
So anyone want to talk about Earth holes?

Or you can ignore gravity, rotation, and magma, and just start digging your way straight through. But where would you end up?

Wow, that Bingham canyon mine, utah is HUGE.

Google earth that one for sheer size.

I see Hill has been busy in Montana. Check out Butte Montana and the Berkley Pit there.

Hill - for a google follow-up you might want to point to Anaconda Montana and the smelter clean up going on at the east end of that town. Its where alot of the tailings from the Butte mine ended up. Its very visible with Google earth.

Thanks for the info. I'll check it out.

A great link.

Unfortunately, it isn't in highest resolution. Link> Google Earth Community: The Blue Hole, Belize

Way too new for Google Earth. Those views are months to years old as the whole globe is updated a little at a time. The exception is special cases like coverage right after Hurricane Katrina to help to visualize the damage, and the recent and ongoing search for Steve Fossett's downed plane.

Those holes in Peru are interesting. Zooming and panning around the area is fun. I hadn't seen them before.

Thanks, I'll check it out when I get home tomorrow. No GE allowed at work.

I figured as much, but did not know the dates of the GE images. Thanks for the info. Regarding sinkholes, are there others that can be seen with GE that you know of?

The most plausible theory I have read is that they are the result of ancient gold prospecting.

Could it be glacial in origin. Anybody have any other ideas?

Use the search page to look for "sinkhole". I get 154 hits - though not all are original posts. BTW, I didn't realize the Guatamala City sinkhole occurred in February. Here's a link to the post > Google Earth Community: Giant Guatemala City Sinkhole
Imagery still doesn't show it but it looks like the location is nailed down pretty well.

The holes look too organized for gold prospecting. And I don't thing there have ever been glaciers that close to the equator at sea level since the time of multicellular life on earth.

Big pit mines are dramatic. Up close, even smaller pit mines and strip mines, and stone quarries (which are essentially pit/strip mines where the waste (slag) is what’s being mines), are impressive.

Growing up in southern WV, USA, my friends and I were fascinated by abandoned mines and quarries. Oddly, a small granite quarry existed (at about 37 15 37 N 81 11 49 W), embedded in the residential section of my childhood home of Bluefield, encircled in the mid 20th century as the town expanded southward to the edge of East River Mt.

Sinkholes were (and possibly still are) popular kid destination, too – the vicinity is riddled with small limestone caves (the best known being the “Beacon caves”), especially near the mountain. Such small, shallow sinkholes tend to quickly erode and grass over, appearing within a decade to be just a normal feature of the usual hilly terrain.

This reminds me of a pretty famous calculus problem, “the hole problem”, from which comes the roughly 5080 s “orbital period” of an object falling thought a hole between any two points on the Earth’s surface. An interesting variation is that this period applies not only to freefalling bodies, but to bodies on the inclined plane defined by a straight line connecting any two points, so a car on perfectly frictionless track (including no air drag) will take about 0h:42m:20s to “fall” between any two points on Earth, whether they are 2 meters, 20 km, or 20,000 km apart. The 1966 Time article “To Everywhere in 42 Minutes” describes some interesting possibilities raised by then young-ish mathematician Paul Cooper, including the use of non-straight tracks, and possibilities for “straight-line tunnel travel” on other worlds (on the Moon, the travel time is 53 min). Such a scheme might be more feasible on the Moon, as there’s no air drag to require evacuated airtight tunnels, lots of nice craters in offering long unobstructed near-surface straight lines, potentially easier conditions for big excavations, and hardly any threatening seismic activity. A neat application for an Inductrack?

Fun to also post about what Earth holes may or may not exist, and what goes into them. ..............

With two additional reliable and confirming reports of local people (and following up with additional local leads) who have seen Mel's Hole first hand, - showing us on a map the same specific area Red Elk led us to - we are no longer asking IF the hole exists but where it is exactly and pinpointing its location. Even if we excluded the validity of Mel's story, we cannot deny these additional local reports. The significance of Mel's Hole is that it could very well be the world's deepest volcanic vent hole - a worm hole and as such not only the best indicator of volcanic activity in the Cascade range for the immediate safety of the Northwest and the Pacific Ring of Fire volcano range but of huge geological significance giving us the best access for instruments to study our earth's mantel.

That's wacky Turtle.

Mel: Now as you can imagine this is all Native American land around here and so one of the line of inquiries d like to make is there anything about this hole in regards to the Native Americans .. that is something I haven t really pursued right now but..

Art: If you had a fatal disease Mel?

Mel: yea?

Art: ...would you jump into the hole?

Mel: I would.

Art: You would? Just based on the dog story?

Mel: It is in my will..

Art: What?!

Mel: ..that if I meet my demise..

Art: That you would be thrown in the hole?

Mel: ...that I would be disposed of into the well.

Art: I m not sure the health department would allow that.

Is anyone aware they have found deep sink type holes on mars?
