Northern rock mouse records gather in three kinds of rugged New Mexico country: the lava and sandstone of the Cebolla Wilderness and El Malpais, the canyon walls of Bandelier National Monument, and the San Mateo Mountains’ Apache Kid Wilderness. Cibola County alone holds 121 of the 281 records, with Lincoln County next at 75.
May and June form one reporting peak, followed by another in October and November. That split is more likely to reflect field effort and detection than two population booms. Night-active mice stay hidden in broken ground, so even suitable places can produce few casual reports.
