Thumb Flat   Picture of the Week

With a basic knowledge of native Arizona plants and observational skills, it’s easy to tell what elevation you’re at in our state. Maybe only Florida is easier because the entire state is below 350′. I’ve written before about how State 48 has all but two of the world’s climate zones; sub-tropic and tundra permafrost. So all you have to do is look at the bush you’re standing next to you for a clue.

For example, compare last week’s picture to the one that I posted today. The tall ponderosa pines you see in Yellow Field thrive at altitudes over 6,500 feet. While the pinion pine in this week’s image—Thumb Flat—is the dominant plant between 5,000 and the appearance of tall pines. My rule is only a rough generalization because there are microclimate pockets all across the state. I can name two places off the top of my head as examples; Palm Canyon in the KOFA Range south of Quartzite and the east slope of the Poachie Range south of Wikiup. The state’s only native palms grow in a mountainside crevice at the first location, and the latter has saguaro and pinion pine intermingling on its slopes.

When Queen Anne and I visited Williams, it was only natural as we drove down the south slope of the dormant volcano to see ponderosa pine replaced with stands of juniper. As the White Horse Lake Road descended even lower, the juniper became sparser. By the time we reached Thumb Flat—as it’s called on the map—individual trees had stood alone in the wildflower-covered fields.

Here I spotted this beautiful alligator juniper, which made me stop Archie and get its portrait. I think this specimen would be a prized possession in anyone’s garden. Probably the only reason this tree isn’t already in somebody’s front yard is that it’s in the middle of the Kaibab National Forest.

In this week’s featured image that I call Thumb Flat, I like how the foreground is darker in color from being in the shade of a cloud. It contrasts nicely against the bright white background cumulus clouds. The wildflowers are the same as in last week’s image, but you can see how much more dull they are when they’re not in direct sunlight. In this case that’s OK because they’re not the subject here—this week, they’re only playing a ‘walk-on’ part.
