Happy Thanksgiving!

Do-It-Yourself Decorating
Autumn Arrangement
 Here's to a wonderful Thanksgiving to all my dear readers! The fall colors in this bright bouquet seemed just right for this year's celebration. I recently made this arrangement from a bunch of odd flowers my mom picked up from our grocery store. It brightened the room of my grandpa who is in the nursing home recovering from hip surgery. This cheerful bouquet reminds me of a passage from Psalm 95:1-2 to bless this Thanksgiving season:
 
Oh come, let us sing to the Lord!
Let us shout joyfully to the Rock of our salvation.
Let us come before His presence with thanksgiving;
Let us shout joyfully to Him with psalms.

Iron Oxide Crystals

Ohio History
Crystal Combos
As we advanced into the third underground "room" of crystals, our tour guide pointed out the unique "dual formations" in the Caverns. They are combinations of iron oxide sediment at the top and regular calcium crystals at the bottom. These multi-colored formations are thus a mixture of rusty brown and pure white. Can you see both stalactite and column dual formations in the picture above? According to the Caverns' website, these formations are quite rare but Ohio Caverns features a large number of them.
Iron Loopholes
There was plenty of other iron in the underground caves as well. The orange color in the left side and center of this picture is actually hundreds of teeny crystals formed by the iron oxide. And in the back center I believe is a solid iron column, though it's hard to tell. These orange hues were so pretty - it was hard to believe it's the same process that leaves orange hard water stains all over the shower walls!

Crystal King

Ohio History
Champion Crystal
This is the prize crystal of the Ohio Caverns, accurately named Crystal King. Measuring almost five feet long, the crystal stalactite is estimated to weight over 400 pounds. It was amazing to imagine that much weight hanging from such a small top! It is said to be the largest free-hanging crystal stalactite in Ohio, unique in its pure-white color and perfect formation. Crystal King hung back in a rock wall recess, and though we couldn't see it, there is a corresponding stalagmite in a pit far below. According to the Ohio Caverns website, the crystal drips once every 7 to 8 minutes...we didn't stay that long to watch!
White Light
And now enjoy the no-flash, "natural" lighting view of Crystal King. The shadows and highlights are something else. Also, at this point we were as far underground as the tour would take us, about 103 feet. I can be impressed now that I'm not actually in the cave anymore!

Crystal Shapes

Ohio History
Hidden Pictures
Moving into the second "room" of crystals, we began to spot some interesting varied shapes. Don't you just want to light that birthday candle in the center of the photo above? I see an arm and hand reaching down to the left of the candle, and a little orange egg on the right. But did you spot the water spigot on the far right side? This amazing crystal was hardly three inches tall, yet it looks so real! Except for the missing handle...

Light Effects

Ohio History
Crystal Silhouettes
Flash photography brings out the most beautiful colors and detail in the Ohio Caverns rock and crystals. But it also misses some of that "underground mystique." So here are a couple pictures using only the lights featured in the cave. Our tour guide assured us it was all white light, and any colors we saw were natural to the crystals. I love the silhouettes in the picture above. Doesn't it just feel a tiny bit like you're looking into the mouth of a shark?
I couldn't help thinking about a carrot when I took the picture below. I'm pretty sure that crystal is less than 12" long but it sure looks amazing.

Anatomy of a Crystal

Ohio History
Stalactite vs. Stalagmite
Here are a couple larger crystals, still on those rock shelves I described. Do you know the difference between a stalactite and a stalagmite? Truth to be told, I didn't until our tour; now I don't think I shall ever forget them. As our tour guide said, stalactites hang tight from the ceiling; stalagmites might reach the roof someday. So the stalactites hang down; the stalagmites grow up. I wonder how long it will take the one above to reach the ceiling. Will the stalactite reach the floor first?
Columns of Crystal
There was one more kind of crystal formation we saw as well: columns. I suppose the little columns in the picture above are stalactites that have reached the floor (or stalagmites that have reached the roof?). In this particular picture it almost looks like someone has squirted caulk all around the top of the crystals and it's oozing and dripping out! Or is that well-done upside-down meringues?

Rooms of Crystal

Ohio History
Crystal Shelf
 After a good 10 or 15 minutes of walking through rock-walled tunnels, we got our first glimpse of real crystals. The tour we took, called the Natural Wonders tours, traversed through four different "rooms" inhabited by hundreds of crystals. So above is the first "room." The crystals hung from low rocky roofs and grew from corresponding rock "shelves" about four to five feet high. The space between the two rock ledges ranged from two feet to six inches. It felt like looking into a kaleidoscope: rainbow-colored rock backdropped hundreds of miniature white "icicles." A mesmerizing view, to say the least.

From Mud to Cave

Ohio History
Crystal Water Droplets
Here are some of the first crystals we saw. They were tiny - only about an inch long - and hung above a rocky ledge at eye level. Did you spot the drop of water on the end of the foreground crystal? We watched (and used our imaginations) as each drop of water trickled down to leave its own tiny deposite of minerals, lengthening the crystal by . . . oh so little. The Ohio Caverns maintain a steady temperature of 54 degrees all year long, allowing a constant cycle of moisture. Indeed, although it felt both damp and chilly, this environment would be welcome in the freezing winter or summer heat!
Mud Division
 Our tour guide explained that when the caverns were first discovered, the tunnels were actually filled with mud anywhere from 3-6 feet deep. Many hours of man power drained the mud and poured the tunnels with concrete walkways. If you look closely at the picture above, you can see proof of the mud. Can you spot the crystal hanging from the ceiling a ways back that looks to have a bunch of mushroom roots at the bottom? Well, that was actually the base of the crystal, growing atop the mud. Now the mud is gone, but the crystal remains, no longer "planted" but now suspended.
