I saved this link to a discussion of this subject that took place in 2007 on the Muzzleloader Magazine message board. Scroll down about half a page to the entry by "GreyWolf" for a good summary of his research.

:cursing: The link works fine until I try to paste it here. Maybe you can get there by Google.
Here's the info Gary was trying to provide a link to (I be Greywolf over there)
The first workable percussion system is dated at 1805 and this system, the scent bottle with pellets, was patented in 1807 by Reverend Forsyth. Nobody knows for sure who invented the first cap, but workable models were around by 1815 and it was first patented in 1823. The early workable caps were made of steel as noted above and then copper foil and later of brass. The primer itself was, Fulminate of Mercury, which was used in some cartridge primers as late as the early 1960's (30-06 competiton ammo), although they weren't widely used after the first World War.
As for little or no cap locks in America and especially in the West - here's several period references that suggest other wise......
1) In 1827 the "American Shooter's Manual" noted that eastern sportsman were almost exclusively using shotguns fitted with percussion locks.
2) General Ashley 1829, "I have used the percussion locks locks but little, but believe them admirably well constructed for general use, but more particularly for the prairies, where the severe winds and rains prevail at certain season of the year."
3) In Sept 1831 and again in December 1833, the US government ordered for the Western Indian trade, some 2150 guns from Deringer. One shipment included," 217 percussion and 93 flintlock rifles complete, at $12.50 each: 217,000 percussion caps at 80 cents per thousand; [and] 310 woolen covers at 37 1/2 cts......"
4) In 1834 shortly after founding Fort Hall in Idaho - N. Wyeth and his party - "percussioned three rifles, our powder being so badly damaged as to render flintlocks useless."
Here's Nat Wyeth's journals/correspondence -[url] http://roxen.xmission.com/~drudy/mtman/html/nwythint.html
5) August 1837, Osborne Russell's hunting companion, "shot a Grizzly Bear and bursted the percussion tube of his rifle which obliged us to return to our comrades...and make another tube." Journal of a Trapper -

6) Famed Mountain Man, Jed Smith was killed by the Comanches along the Santa Fe Trail in 1831 - the pistols taken from him had been converted from flint to percussion and his rifle was reportedly a Hawken caplock.
7) H. H. Sibley after a hunting mishap, 1839, "........Now my opinion...is that, any man calling himself a sportsman who will not use a percussion, when he can procure one, in lieu of a flint-lock gun, should be furnished with a strait jacket at the public expense."
8) The US Armies Hall breechloaders were first fitted with percussion locks in 1831 (surprisingly early considering that the miltary of that period was notoriously slow about modernizing). Still most of the world's armies, including the US, had by and large had at least begun switching to caplock firearms by 1840-42 (the so-called M1841 Mississippi Rifle was the first such widely used USA long arm - it was in wide use by the mid-1840's.) .
9) It didn't take long for the percussion system to move west, early in 1832, John Martin of Little Rock, Ark. advertised, " Guns and Pistols with common locks, fitted with percussion locks, at the shortest notice." - In other words he was advertising that he could convert a "common lock", i.e. flintlock, to percussion at short notice, indicating that there was a plentiful supply of not only parts, but caps as well.
10) American Fur Company brigade leader Lucien Fontenelle bought his Hawken in 1832 and it was definitely a percussion since he also bought caps at the same time.
11) Mtn Man Kit Carson was an early (circa 1838-9) advocate of Colt's percussion revolvers and longarms, as were the Texas Rangers (1837-38) and Josiah Gregg (1839) and his brother who were outfitted with Colt revolving pistols and rifles.
12) Warren Ferris mentions using a cap lock during his tenure of 1830-35 in the mountains.
By the later 1830's and early 1840's the use of the cap lock was generally well on it's way to making the flintlock all but obsolete except amongst the Indians and some of the old die hard frontiersman. Still Western Indian trade guns at least were produced with flintlocks well into the late 1860's, but this may not so much have been due to the lack of caps, but rather their method of hunting buffalo on horseback, where the flintlock was easier to load and self-prime.
Availability of caps in the west: Hansen's book "The Hawken Rifle It's Place in History" has several references to caps being available in St Louis at least by 1830, just 3 short years from the time they were considered de riguer in the "East" (in 1827 the "American Shooter's Manual" noted that eastern sportsman were almost exclusively using shotguns with percussion locks and by 1830 rifles as well).
By 1834-35 several vendors in the St. Louis area were advertising quantities of caps in the 100,000's and within another couple of years later they had them in the millions. As to getting them out west, although it may seem on the face of things that such "luxuries" were hard to get many rendezvous trade lists don't necessarily uphold this view. Not only that, but by the late 1820's and early 30's several forts and trading posts, Uncompaghre (1826), Laramie (1834), Union and it's satellites 1829, Hall (1834), Bent's, (1834), etc. as well as the Santa Fe trade made things more easily available.
Regarding wet caps - it's one of those sort of "myths" that just won't die. Early on waterproofed caps were being made and sold. Heck even modern primers must be waterproofed.....As for the ability to "just pick up a rock" reason for using a flintlock rather than a caplock - not only is not as easy as it sounds - there are many areas in the west where suitable rocks aren't easily obtained and then it must be knapped properly to work, plus thousands of flints show up for sale on the RMFT era trade lists.
Besides following that logic - a bow and arrow or spear would be the better choice, since both powder and ball can be lost (or in the case of powder ruined) and neither were necessarily any more easily obtained than caps...
