About this layer

Stream sediment samples test material collected from creek or river beds. A higher reading can be a clue to mineral-bearing ground somewhere upstream. Compare nearby samples and the upstream drainage; the sample point is not necessarily the source.

What it is for

Compare readings along the drainage and with the geology upstream. Check the legend for the element and units.

Limits

Sediment can travel and mix with material from different sources. A sample point is not a precise source location.
