Roger Hart... says these stumps are almost 4,000 years old... "Curt Peterson and I published a radiocarbon on a sample taken from the Arch Cape stumps in 1998," Hart said. "The age is 3,660 with an error of 70. This means these trees died at that time, were buried in sand, and have been preserved under a cover of sand until now. From the photos it appears that the stumps are more extensively exposed now than in 1998."
So now they're 3,669 years old. [rimshot!] The RC age is *not* a reference to when the trees died, but rather to the age of the ring (or rings) which were tested. The catastrophe which buried all this stuff is less than that -- perchance 3,450 years? ;')
