This is a thorny currant that grows at middle and upper elevations called gooseberry currant (Ribes montigeneum). It grows in western North America, and a pretty pink flower blooms in spring and early summer. Later a red berry appears that is sought after by wildlife.

This spreading bush with attractive leaves and whitish-pinkish flowers is wax currant (Ribes cereum), a member of the Goosefoot Family (Grossulariaceae). Later in the season, small berries appear that can be used to make jelly. Generally this bush grows from 6,000-9,000 feet in our area, but I found it next to a lake at 10,230 feet.
Here you can see the fan-shaped leaves and the flowers in clusters.
This yellow flower is a delight to see because it is a precursor to a tasty treat--the golden currant (Ribes aureum). This member of the Gooseberry Family (Grossulariaceae) is common along wet areas. 
In a few weeks, the flowers will fall off and a small fruit will grow. It is bright red when it is ripe.
Golden currant often grows in close association with Woods' rose (Rosa woodsii), another plant that likes moist areas or a shallow water table.
