In the foreground, we see pulverized Lookingglass silt/mudstone, mixed with manure. In the mid-ground are numerous bebe vines. If I recall, the fellow showing us around said that it would be a few years before these really started producing- unlike much of agriculture, wine is a long term investment and commitment. You can't switch to a different crop next year, if you think the market will be better for something else. Like the geology embodied in this recent set of photos, wine is about the long run.
