Identity HelpSanta Monica Mountains - Malibu

I found this crystal mountain biking in the volcanic part of the Santa Monica Mountains. All three of these shard (I'll post more pics below in reply) were near each other and are only the size of my thumb nail. Any clues as to what they are? I find a lot of quartz in this area but clear, is this ironized quartz maybe? Never seen anything like here, the soil was dark volcanic brown powder dirt on the path. I usually find my rocks in creek beds, not sure where this came from.
