We had an upslope storm come and go here in Colorado. It left solid phase hydroxylic acid all over the place. Fortunately, my Jeep has a special traction setting for that situation.

State officials have attempted to deal with it by using Group 1 and Group 2 metal halides as well as diaminocarbonyl to affect the colligative properties of the hydroxylic acid crystals.  This leads to an increase in the friction coefficient of the asphaltene and hydrated calcium oxide conglomerates used by motorists.
