Thunderstorms

In some languages, the verb 'to do' and 'to make' are identical.  Hacer in Spanish.  Faire in French.  In German and English, there are two verbs.  Choosing when and how to use either one somehow doesn't seem consistent.  You make change.  You do the dishes.  Make a salad.  Do the cooking.  Make your point.

When water vapor rises and condenses, it releases the the energy it held while it in its vapor phase.  That released energy is the 'latent heat of fusion.'  This heat drives the clouds higher and bigger in a chain reaction that builds a crazier and crazier show until suddenly you have electricity and ice.  Thunderstorms can make sheets of rain.  They can do damage.  They can make walls of rolling sound.  They move water and energy all over the place.  (Or are they themselves just moving water and energy?)  Puddles can evaporate and join another thunderstorm tomorrow.   In a way, what thunderstorms really do is to make themselves.

Cathedral Spires

Once you get onto safe ground for awhile, it's hard to remember how different the tops can be.  When we fled down late off the side of Sharkstooth, this massive cluster of spires was looming over my shoulder.  I felt like we were being chased back low, tumbling over the talus.  Looking backward, a strange night veil had closed and the rocks seemed to be smoldering darkly in starry scariness.  Even though we had just been on top of the thing, it was suddenly a total mystery again.
