The particles were at the bottom of a trench that had been previously dug out by the robotic arm and scoop of Phoenix. Informally called “Dodo-Goldilocks,” the trench had been formed by the actions of the Lander on June 15, 2008 (Sol 20, the twentieth Martian day since Phoenix had landed).
However, when the Lander looked at the trench four days later (June 18, Sol 24), the white pieces were gone.
Added to this bit of information, mission scientists also believe the Phoenix’s robotic arm came into contact with an ice layer at a different location in which it is digging a trench. The arm hit the hard layer, and after three tries stopped trying to dig. Such an action has been programmed into Phoenix so that it stops digging whenever it hits a firm layer, such as ice.
The new trench, dubbed, “Snow White 2,” is located to the right of “Snow White 1.” Both Snow White 1 and 2 are within the “Wonderland” site.
Robotic arm co-investigator Ray Aravidson (Washington University, St. Louis, Missouri) states, "We have dug a trench and uncovered a hard layer at the same depth as the ice layer in our other trench." [University of Arizona]
