The complete county distribution, spread across 28 Utah counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Montane shrew records fit Utah’s cool Wasatch and Uinta meadows better than the open salt flats or refuge water named by broad location labels. Damp ground, dense cover, and stream edges create small habitat pockets within a much drier landscape.

July through September holds most reports. High-country access and late-summer fieldwork probably help create that concentration, and the record gap in winter says more about detection than confirmed absence.
