Well ... It sounds a bit like MERRANO OF THE DRY COUNTRY, a short story as well as a dramatized Audio Book.

When Miguel Merrano first came to Mirror Valley, the land was green and lush . . . and off limits to Mexicans. Ranchers such as Tom Drake and Joe Stangle tried to drive Merrano out, to fence him out; and whe he warned them that greed and overgrazing would ruin their land, they refused to listen.

Now Merrano's predictions have come true. Mirror Valley is so dry it's about to blow away. The cattle are hollow-ribbed and dying. And the ranchers are broke . . . flat broke. Only Merrano's ranch is still thriving. As the ranchers watch him pay for goods in gold and sell his cattle at a mighty profit, their hatred grows and festers . . . until they draw their guns in a desperate act that will pit daughter against father, friend against friend - an act that could tear the valley apart forever . . .
