I'm intrigued by a time-lapses, especially those that involve snow. I watched this 5 foot dump in Big Bear and this Sunshine Village time-lapse, then decided I might attempt my own.
The technique(s) I used were pretty rudimentary but fairly effective. Basically I visited the MT DOT site and downloaded an image from their Lolo Pass webcam whenever I could remember to do so. I left a huge gap during the month of March, which just so happened to coincide with a serious lack of snowfall. My original intent was to capture the massive snow berms (and their ebb/flow) that usually stack up on the side of the highway. This winter however, was not all that impressive. Nonetheless, it is interesting. Let me know what you think.
