Not much was in bloom, just a couple small patches of white flowers: milkmaids, miner's lettuce, and this. On first glance I thought it was cowparsnip (Heracleum maximum), but the flowers didn't look quite right to me and there weren't any leaves. After I got home, I flipped through my Wildflowers of Garland Ranch by Michael Mitchell and Rod M. Yeager, my personal favorite local flower guide. I double-checked online (see embedded links in the ID above). Michael and Rod also do an impressive online MontereyWildflowers site that I tend to forget exists. It looks like they've made a lot of improvements in the past few years.
