Martian Crocus Region

This plot shows the cap edge as a function of season. The data used was 30 µ mpre-mapping TES data. The contour lines are spaced at 10 degrees of L_s, starting with 215 as the dark blue contour. A small region between L_s 275 and L_s 295 has been shaded to indicate that this region has a large error in our estimate of the cap edge. A table below has been provided so that you can easily convert L_s into a Earth calendar date.
