We spent our last day on the warm rain-shadow side of the Cascade Mountains as we continued west. Spring is in full force, or as full as it can get with nine inches of rain a year. The green grass-covered hills are already turning pink and soon to yellow as temperatures climb and the spring flora succumbs to drought. We admired the tenacity of these plants as they bravely flowered with minimal resources. From the brilliant canary-yellow of the arrowleaf balsamroot flowers to the azure blue of the native larkspur, the colors of the rainbow were represented in the delicate structures of flower petals. Spring is in the air and on the hillsides as well.
