The Surface Stereo Imager on NASA's Phoenix Mars Lander took this false color image on Oct. 21, 2008, during the 145th Martian day, or sol, since landing. The white areas seen in these trenches are part of an ice layer beneath the soil.
The trench on the upper left, called "Upper Cupboard," is about 60 centimeters (24 inches) long and 3 centimeters (1 inch) deep. The trench in the middle, called "Ice Man," is about 30 centimeters (12 inches) long and 3 centimeters (1 inch) deep. The trench on the right, called "La Mancha," is about 31 centimeters (12 inches) and 5 centimeters (2 inches) deep.

The trench on the upper left, called "Dodo-Goldilocks," is about 38 centimeters (15 inches) long and 4 centimeters (1.5 inches) deep. The trench on the right, called "Upper Cupboard," is about 60 centimeters (24 inches) long and 3 centimeters (1 inch) deep. The trench in the lower middle is called "Stone Soup."

but that looks like an archaeological dig
you can tell those are structures or remains
not dirt and ice!
The Robotic Arm took a second scoop full of soil and revealed whitish material at the bottom of the dig area informally called the "Knave of Hearts". The Science Team is debating whether this is a salt layer or the top of an ice table. Image was taken by the Surface Stereo Imager on the ninth day of the Mars mission, or Sol 9, (June 3, 2008) aboard the NASA Phoenix Mars Lander.
This image shows oblique views of NASA's Phoenix Mars Lander's trench visualized using the NASA Ames Viz software package that allows interactive movement around terrain and measurement of features. The Surface Stereo Imager images are used to create a digital elevation model of the terrain. The trench is 1.5 inches deep. The top image was taken on the seventh Martian day of the mission, or Sol 7 (June 1, 2008). The bottom image was taken on the ninth Martian day of the mission, or Sol 9 (June 3, 2008).
This image shows NASA's Phoenix Mars Lander Robotic Arm work area with an overlay. The pink area is available for digging, the green area is reserved for placing the Thermal and Electrical Conductivity Probe (TECP) instrument. Soil can be dumped in the violet area.Images were displayed using NASA Ames "Viz" visualization software.
