Lone Star Geyser erupting just as we approached
having a warm bath in Shoshone Creek near a hot spring
seeing Shoshone Lake, one of my favorite places on earth, from many perspectives and in many different lights, and waking up our first morning on its south shore to two sets of bear prints, one large, with long claws, and the other small
watching bald eagles and pelicans by the lake
touring the Shoshone Geyser Basin, which we haven’t seen since we skied there years ago

The Smell of Approaching Rain!
Australian scientists Isabel Joy Bear and Richard Thomas identified and named the smell of rain approaching: they called it “petrichor … the unique odor which can be regarded as an ‘ichor’ or ‘tenuous essence’ derived from rock or stone”. This article from EarthSky news describes their discovery in the 1960’s. Petrichor is the scent the earth itself releases when humidity is present in the air, particularly after a dry spell. Humidity fills pores in the earth’s surface with minute amounts of water. The “oil” or essence is released from the surface into the air. Rain and wind accelerate the process. An Indian perfumery called this essence “matti ka attar” or “Earth perfume”.
Now scientists at the Massachusetts Institute of Technology have released a slow-motion video of this process in motion.
It is raining here, thank goodness, and that earth perfume sure smells good!! I’d like a bottle of it.
