Instead, it appeared that the trees had been bent and twisted away by some powerful lateral force. There was no evidence that a fire had passed through-none of the surviving trees were charred, nor were the few remaining tree stumps. It was clear that at some point in recent history, an unknown, massive force had scraped the shores clean, and the vegetation was only beginning to reclaim the land. There was some vegetation growing below the distinct line, but it was all upstart grasses, saplings, and such. While surveying a remote fjord known as Lituya Bay, Miller found that the dense, mature forest that surrounded the bay ended abruptly hundreds of feet upslope of the water.
