We departed right on time around 1pm at the parking lot. It took about 25minutes for us to get there with not much of traffic. The hike was overall easy to moderate. It was good to see plants we saw in the previous hikes since it was a good review for our field quiz. The most plant family we saw was apiaceae, boraginaeceae, and brassicaceae. One of the memorable plant I found out in this hike was Franciscan Wallflower. The shape of the 4 petals with beautiful white yellowish color made me to keep looking at it. It was sad to hear that this is currently endangered plant. The best part of this trip was In n Out. This was the reason why I took this class! It felt more amazing after the workout.
