By the definition that cryologists and climate scientists use an ice age is any period when there are significant ice sheets on the Earth. Like Antarctica and Greenland. Within the ice age there are cycles of glacials when the continental ice sheets advance and interglacials when they retreat./pedant
But in the popular vernacular ice age refers to a glacial cycle so it's an easy mistake to make.
A stack of 10 dollar coins is only 0.8 inches long and about an inch in diameter. I often carry that much in my pocket without noticing. I'll bet you can't fold up a dollar bill smaller than a dollar coin.
Multi-day is a different world. You live in the moment and forget about the outside world for days at a time. I used to backpack in my younger days but rafting gives you the carrying capacity to bring steaks and beer along. Most of the multi-day whitewater rivers in the US are west of the Rockies. If you're interested in a shorter trip than the Grand Canyon I particularly recommend the Rogue River in Oregon and the Middle Fork of the Salmon River in Idaho. If I don't get a permit for the MF Salmon in 2013 I'll be doing that river with an outfitter that lets me row my own boat. It's as special a river in a different way as the Colorado in the Grand Canyon.
Well, on a river there's really no way of getting lost. You're on it floating downstream. The Colorado in the Grand Canyon is a well known river with lots of famous landmarks (well known in the rafting community) so it's pretty easy to keep track of where you are. We had some good guide books along plus a couple of people who had been down before. After doing this for the past 27 years I have no need to hire a guide. I've run a lot of rivers over the years including the Snake River in Hells Canyon and the Main Salmon river that are similar sized rivers to the Colorado although not nearly as long and not as many rapids. My longest trip before this was 8 or 9 days and around 100 miles. Most years I run 6-12 whitewater trips although most of them are just day trips. 2 or 3 of them will be longer multi-day trips.. Where I live in the Willamette Valley of Oregon there are 7 rivers to run within about 3 hours drive including one that's just 35 minutes from my house so I usually get at least one trip a month from April to October and occasional trips in the other months.
In order to get the permit to run the river I had to enter a lottery where 10,000 people or so compete for around 500 launches per year. I got lucky and got one and was able to invite up to 15 others along (we had 10 people total). The biggest difference between this trip and the other ones I've done it planning the food for 10 people for 23 days on the river. The rest of the equipment was the same as I use all the time (except I rented a larger boat than the one I own because of the extra food we had to carry).
It sounds like you're interested but have no experience. If you'd like to float the Colorado I'd suggest you go with one of the commercial outfitters. They offer a number of options including big motorized rafts that carry 15-20 people and get you through the canyon in 5 or 6 days (too fast in my opinion) or rafts and dories that carry 3 or 4 people and take 13-18 days. Costs per person are a bit under $3000 for the motor trips to around $5000 for the longer trips (the cost for our private trip as around $1500/person). I would recommend O.A.R.S as an outfitter. If you'd like to take it up yourself it helps if you live somewhat near to some whitewater rivers.
The other problem with the Susan B. Anthony Dollar was it had a milled edge like a Quarter. The Sacagawea and Presidential Dollars have a smooth edge so it's not hard to tell them apart from a Quarter.
The new style dollar coins have been around for a while. The Susan B. Anthony dollar was first minted in 1979 but it was too much like a quarter. The Sacagawea dollars in 2000. Here's the Wikipedia article on them.
I've been trying to eliminate dollar bills from my wallet just because of the issues mentioned in the article. I go down to the bank every few months and get several rolls of dollar coins and use them to keep from getting dollar bills in change. You can still get $2 bills too. Of course many people are going all electronic nowadays but it will be a long time before physical currency completely disappears if ever.
Yes, we launched at Lee's Ferry (about 10 miles below Glen Canyon Dam) on March 27th and 270 miles later we took out at Pearce Ferry on April 18th. If Lake Mead had been at full pool we would have had about 40 miles of lake to cross. Once we got down to where Lake Mead used to be there were silt banks along the river 30-50 feet high in places. I've been whitewater rafting since the mid 70's but that was my first time through the Grand Canyon.
LA gets a large share of water from the Colorado River too and I think Phoenix as well. The Colorado River flow has been blow normal every year except for 2 since 2000.. Both Lake Mead behind Hoover Dam and Lake Powell behind Glen Canyon Dam are well below capacity. Lake Powell is at 85 feet below full and 54.5% capacity. They keep Powell a little fuller because they can always send it down to Mead if necessary.
The people who will really be hurt by the dry conditions are the farmers in Southern California and Eastern Arizona. They are completely dependent on Colorado River water.
(I pay attention to the Colorado because I'm a whitewater rafter and I got to row a boat through the Grand Canyon last spring. What an incredible journey.)
Don't make the assumption that I'm voting a straight Democratic ticket. I've voted for both of the major parties in the past although it's been more than a decade since the R's put up a candidate sane enough for me to vote for. I vote for third party candidates often too including this past election.
1000 years ago Greenland had no ice as well because the Vikings were living on it.
That is trivially easy to disprove. If Greenland had no ice 1000 years ago then sea level would have been 20 feet higher than it is now. If it had had even 5% less ice sea level would have been a foot higher then. It wasn't. There were a few areas on the extreme south of Greenland where the ice may have been back another mile or two from where it is now and the Vikings could eke out a living with livestock but Greenland has never been completely ice free for at least 100,000 years and probably much longer than that.
Do you seriously think if McCain had been elected things would be any different? History shows that the national debt generally grows more under Republican administrations than Democratic administrations. Republicans only make a big stink about the debt and deficit when they are out of power.
The enlargement of the sub-tropical zones because of Hadley cell expansion means most of the southern USA, particularly from Texas westward will probably get drier.
You're just grasping at straws there. The vulcanologist's estimates of yearly volcanic emissions cover all of them whether associated with a noticeable eruption or not.

You must be pretty young.
Oh come on! It's corrosion resistance and electrical conductivity make it by far the best material for a whole host of applications.
And coincidentally 5'10" is 178 cm (rounding 177.8 cm up).

Maybe you're right but if it was strictly a business decision dollar bills would have disappeared years ago to save around $150 million / year.

Well, you're right, I've never had that problem either. But some people aren't as perceptive as we are, eh?

True but the ones before the Susan B. Anthony dollar were much larger.

Dollar coins at the strip club sounds both dangerous and hilarious.
And I'll just say you sound like a cheap bastard to me.
Somehow I screwed up a link in the previous reply. Before the Lake Powell link I wrote:
Lake Mead is currently 102 feet below full pool and 51.5^ of capacity.

If they found Mardi Gras beads the name would be appropriate.
