天山新题第2题仍有疑问

2. Those who have visited the Grand Canyon have typically seen layers of sediment in the gaping canyon, with different colors that mark the passage of time like the rings in a tree trunk.

这题with短语修饰什么?

还有一个问题,with短语在修饰中是否有限制?比如只能修饰主语,或者只能修饰就近的词?

谢谢!

with短语应该是修饰layers的，宾语中心词。

我是凭感觉。我觉得：with短语作为layers修饰语，由于几个修饰语，没折，只好放后面，用，隔开。
