engelmannii (Engelmann Spruce)
Pinaceae (Pine Family)
Just above 11,500 feet ("tree-line" in the Four Corners area) trees are compressed and distorted by wind, the short growing season, intense sun, and snow pack. These forces shape trees into krummholz (German for "crooked woods": the dwarfed, compact, crooked trees, some of which appear to be shrubs in both photos).
Some slightly taller ten-to-fifteen foot krummholz are wind-blown into "banner trees" -- trees with no limbs on the wind side.
Krummholz may appear to be relatively young because it is so small, but, to quote the National Park Service, "Well-established krummholz trees may be several hundred to a thousand years old".
Krummholz provides a haven for flora and fauna that cannot thrive in the nearby intensity. Krummholz is also a haven for humans wanting to picnic out of the wind.
