Plants Struggle for Survival in the Dry, Powdery Volcanic Dust.
…Exposed to the Intense Sunlight, Hill Tops & Slopes Are Deadly to Plant Life.

“At the motorcycle I unpack everything, get out the long underwear and put it on, then clothes, then sweater, then jacket. I’m still cold. .. I step through the spongy dust …. ” (Cont. Next)

5.8 Miles North of La Pine, OR. In addition to the frost, you can see the spongy dust in the photo. While camping there. I had to push my tent way under those pines.
…This was the only place where there was a thin mat of pine needles, so I could get away from the sticky dust! I am sure the rugs of my car still have the residuum of this dust from my shoes!
