outwash

Sometimes the animal multitudes are horizontal, as on Salisbury Plain, a glacial outwash delta densely colonized by king penguins, fur and elephant seals, and kelp gulls.

有些地方动物种群是水平分布的，比如在索尔兹伯里平原，这块冰碛沉积三角洲密集分布着王企鹅、软毛海豹、象海豹和黑背海鸥。

Hmm. At the time our colleague suggested that maybe these were delta deposits or possibly glacial outwash (although we don’t know the extent of past glaciations in the park).

嗯，当时我们同事建议这些可能是三角洲沉淀或者可能是冰川沉积时（尽管我们不知道这个公园里冰期的程度）。
