Jennifer from Penguin Unearthed did that green meme about a tree in her yard, the Port Jackson fig. It sounds like a noisy, boisterous, fecund tree and I would love to see it in person. It is not at all like a ponderosa. I was thinking about this around 4am, after I'd coughed myself awake and couldn't fall asleep again.
Ponderosa trees grow very tall and very straight. Their branches start up high, typically higher than my one-storey house*, so we humans experience them more as trunks than as trees. If you are in a neighborhood rather than a forest, they're like poles; they're background; you barely notice them.
Here's a picture of wee Sasha in our front yard, May 2006. The tree trunk you see in the background is a ponderosa.
And these are baby trees.
I live pretty close to where the mill used to be, so I figure this place was logged in the 1920s, maybe 1930s, which would make the eldest ponderosas about 85 years old. Infants! You can see a more mature ponderosa forest around the Camp Sherman area, which wasn't logged in the same way. Here's Blake alongside Jack Creek in 2002:

The needles of ponderosa starts are the same size as the needles on an "adult" ponderosa, which makes the starts look ridiculous. I mean, in some cases the needles are as long as the tree itself. Young ponderosas -- those my age, for example -- have a black trunk; as they grow older, the bark turns an orange brown. When the morning sun strikes them, they look like gold.
Anyway. That's what I was thinking about at 4am this morning.
*The trees in my neighborhood have been limbed. But still. A person could never climb a ponderosa by grasping onto its lowest branch. (And now a whole lotta Bendites are going to write me with exceptions. But! You know what I mean!)
