I just realized it's been over 30 years since I first visited the Mammoth Site. Which makes me feel old. Then I look at all those ancient mammoth bones and I feel a bit better.
Now, I'm not saying it wasn't impressive the first time I went there, because it was. However, it's more impressive now because in the 30-some intervening years they have (a) built the big, beautiful visitor's center, and (b) done a lot more excavation and discovered a lot more mammoth bones. A LOT more.
