King's Crown: dark red head, and Alpine Thistle: at right upper corner

Spring Beauty: growing under rocks, small white flowers coming under leaves

The Mount Evans Scenic Highway seemes to be running higher into clouds at right upper part.



Dwarf Clover in two tone, purple and white (vs. Alpine Clover: longer lily-like leaves)



Just a green plants: this are the Old-Man-of-the-Mountain in maturing stage before flowering



Whipple's Penstemon: in two color shades of creamy white and purple, Only found in high altitude



Golden Rod: Yellow thick flower



Pinnate-Leaved (Purple) Daisy, Subalpine Daisy, Wild alpine daisy

Stonecrop



Stonecrop (yellow) and Yarrow (white)



Unknown ??



Death Camas: (not the yellow ones) White clumped flowers on long stalks with long narrow lily-like leaves.
When cows eat this flower on field, they are toxic and can be fatal.
Sulfur Flower (or Golden Buckwheat): Yellow



Scattered on the southern slope of Mount Goliath are dead trunks of ancient Bristlecone Pines.



Unknown ??



Dead trunks of Bristlecone Pines here are dated more than 2,000 years.






Bristlecone Pines has purple cone (female cone). They do not need fire to open, not like Lodgepole Pines
In the needles, there are white-colored "resin dots". These dots are specific to the Bristlecone Pines.



Male cones of Bristlecone Pine with pollens



Close up of a purplish cone. You can see the bristles on the surface. Also, White resin dots on the needles.



A forest of living and dead bristlecone pines, in this particular area of the Mount Evans.







Engelmann Spruce (Silver or White Spruce): The needles have soewhat whitish blue hue. Large spruce tree, narrowly conic and spire-like shape, making a good Christmas tree.
Here, at the high altitude, they tend to clump together and form a tree island.
(Any trees will do the same at the tree line that is the upper limit for trees).

Spruce' cone is hanging down while fir's cone is pointing up except Douglas fir.

Looking back the trails



Young Bristlecone Pine



Alpine Sorrel (edible): Alpine Sorrell is fairly common. Its large rounded leaves (shiny smooth green) make it easy to identify. Look for Alpine Sorrel at high elevations in moist, partly shady areas in rock crevices, the edges of bushes, or clearings in trees.



Dusky (Whipple's) Penstemon: white or purple



Strip Barking: the living bark remains on the dead trunk and can live very long time with only a small remaining bark



The living and the dead together. Life goes on in the alpine slopes of Mount Evans.
Rosy Paintbrush (pink), Stonecrops (yellow, left lower), probable Early Spring Senecio (yellow, middle)



A bit of everything, Scarlet Paintbrush (red), Stonecrop (yellow), and Unknown Daisy (purple)
together with the remnants of ancient bristlecone pines.
