Choosing a number of minutes to walk (0-10,000) puts you on a beach, where you can choose a spot to comb. Beaches have rough sand, combed sand (if this spot was already combed by you or another player) and possibly a beach head.

You comb the area and find something kind of interesting, as well as some sand, which is not particularly interesting unless you personally happen to be interested in sand, in which case boy howdy are you in luck. That stuff is everywhere.
