The rain has come especially hard in central California, including the San Francisco Bay Area and Sacramento Valley.

加州中部的降雨尤其严重，包括旧金山湾区和萨克拉门托山谷。

It has evidently been derived from the coast range by way of the tangle of connecting mountains at the head of the Sacramento Valley.

它显然是通过萨克拉门托山谷顶部错综复杂的连接山脉从海岸山脉中衍生出来的。

As if to clinch the hold on California already secured by the friends of free soil, there came in 1848 the sudden discovery of gold at Sutter's Mill in the Sacramento Valley.

——好像是为了巩固已经被自由土地的朋友们占领的加利福尼亚，1848 年在萨克拉门托山谷的萨特磨坊突然发现了金矿。

Toward the middle of the afternoon the main flood cloud lifted along its western border revealing a beautiful section of the Sacramento Valley some twenty or thirty miles away, brilliantly sun-lighted and glistering with rain-sheets as if paved with silver.

下午中午时分，主要的洪水云沿着它的西部边界升起，露出大约二十或三十英里外萨克拉门托山谷的美丽部分，阳光灿烂，雨幕闪闪发光，仿佛铺上了银色。
