For years, my husband has kept a small calendar in his closet where he marks each day he skis and which of them are powder days. From this, he keeps a running tally of his powder percentage each season. I’m not sure whether he’ll ever abandon the old, simple system, but I recently came across a new website that might propel him into the 21st century. lets you keep an online journal of your ski days including the date you skied, the conditions, the weather and the lifts you rode. You can also upload photos from the day, track the exact time that you skied, and note the wind speed and direction. The site also has a vertical calculator for Squaw Valley; enter the lifts you skied and the number of laps on each and it calculates your vertical for the day.
