Around the late 1970’s there was a movement inside the occupation to describe fire patterns by descriptions of their geometric designs (e.g. V-sample, U-pattern, hourglass-sample). The characteristics associated with the geometric designs were sometimes associated with the speed of your fire, such as the angle with the V could be interpreted given that the fire remaining quickly or slow. These geometric shapes remain at this time applied within the profession, on the other hand, most of the myths connected with their interpretations have fallen into disrepute.
