古老的冰川与大海相遇的地方 Where ancient ice meets the sea

Glacier Bay National Park and Preserve

Think of this special spot as the place where two different Alaskas meet—its vast icy north and its verdant maritime south. Glacier Bay is named for this area's dominant feature, the rivers of ice that carve the landscape and periodically calve icebergs into the sea. On February 26, 1925, President Calvin Coolidge declared much of the land around the bay a national monument. But the protected area was greatly expanded in 1980, when a 3.3-million-acre expanse of glaciers, fjords, rainforest, coastline, and mountain peaks was named a national park and preserve.

Pictured here is Lamplugh Glacier, one of the relatively few tidewater glaciers in the park; the vast majority are found inland. Lamplugh is known for its intense blue color—ice and water absorb the red wavelength of white light and transmit blue light, which is what we end up seeing. The thicker and more pure the ice, the more blue it appears.

冰川湾国家公园

把这个特殊的地方想象成两个不同的阿拉斯加人在广阔的冰雪覆盖的北方和苍翠的海洋南面相遇的地方。冰川湾是以该地区的主要特征命名的，冰的河流切割景观，并周期性地将冰山崩解入海中。1925年2月26日，卡尔文·柯立芝总统宣布海湾周围的大部分土地为国家纪念碑。但1980年，保护区得到了极大的扩展，当时一片330万英亩的冰川、峡湾、雨林、海岸线和山峰被命名为国家公园和保护区。

这里的图片是兰普卢冰川，公园里相对较少的潮水冰川之一；绝大多数是在内陆发现的。Lamplugh以其强烈的蓝色而闻名，冰和水吸收白光的红色波长并传输蓝光，这就是我们最终看到的。冰越纯，越厚。
