Hidden Copse

I came across a hidden copse Due east of Rainbow Mountain's peak Made up of several dozen oaks And watered by a nearby creek I don't know how it held its own Against the desert's endless creep Or what kept back the sand and stone When sapling roots were inches deep But given thirty years to grow The sanctuary soon took shape Providing shade for those who go And trek across the desertscape And when I stepped inside to rest The branches grabbed a passing breeze A cooling zephyr for their guest Beneath the tall Mojave trees
