Mt. Tamalpais – Steep Ravine

Location: 37.88355968 N, 122.62686697 W

Site Description: It is a dense redwood forest with many different kinds of ferns.

Species Description:

Family – Liliaceae, Species – large flowered fairy bell (prosartes smithii); This perennial herb has simple, sessile leaves with parallel venations. The stalk is twisted and bell-shaped flowers grow from underneath the leaves. They like to grow near water, as it needs moist soil.

Family – Sapindaceae, Species – Big leaf maple (Acer macrophylum); This large deciduous tree has palmately shaped leaves with a strong venation on the underside. It has special seed pods that will spin like a helicopter if spun in the air which is how they achieve wind dispersal. It is often found near water.

Family – Pteridaceae, Species – Five-fingered maiden hair (Adiantum aleuticum); This fern is located near water and had fan-shaped leaves. The leaves look like fingers, hence the name. The stem also has a brownish-black, almost fake feeling stem which is a characteristic of plants in the pteridaceae family.

Narrative: The hike was pretty long, around 3 miles round trip. The weather was actually very nice which was greatly appreciated. There was a lot of mini waterfalls and creeks along the trail. The views were spectacular as well. There were some very steep edges, hence the name, but it was a lot of fun. Near the end of the trail, there was a ladder. A small group of us went up the ladder and chilled for a few minutes. The hike back was easy and we got to see an amazing view of the ocean.

Narrative: I went to Lands End and walked around the coastal trails. I saw lots of cool plants and took a detour to Mile Rock Beach, where I climbed a rock. There was a lot more stairs then I was anticipating so I was exhausted by the time my hike ended. It was also very windy to the point where my hat blew off and had to chase it. Other than the weather, it was a very peaceful hike and I will hike there again when I have the chance.

Ring Mountain

Narrative: When we got to Ring Mountain, there was a ton of grass which heightened all of our allergies. It was also very hot so we had to make sure we stayed hydrated. There were a lot of cool plants and we even saw some lizards and birds in the area. On the way back down, we took a short break near turtle rock. A few of us climbed on top of the rock. The breeze was nice up there. After the tiring hike, we made a special trip to In-N-Out which was awesome. Everyone got back to the school satisfied and full.

iNaturalist Link: https://www.inaturalist.org/observations?user_id=aachew&place_id=any&verifiable=any

Narrative: When we got to the site, there was a lot of debris on the ground due to a big storm that occurred a few days beforehand. The debris made it difficult to find certain flowers but we were able to find most of them. At one point, we were looking for mouse-eared monkeyflowers. The first person to find it would get extra credit but Dr. Paul found it instead. So no extra credit. There were also a lot of muddy areas so we had to walk carefully. The weather was really nice as well.

Narrative: 

We drove around 45 minutes south of San Francisco to San Pedro Valley near Pacifica. It was cold but sunny so it was a nice day to hike. There was a lot of poison oak along the trail so we had to be careful when looking at the other plants. When we got to the top of the mountain, the view was amazing.

It eventually turned into hail which was super fun for the class. It was also very cold. We came across many interesting plants and also a lot of poison oak. We were careful not to touch any of it. As we got closer to the Golden Gate Bridge, we saw a purple flower called Coast Rockcress. The view of the bridge was amazing so I took lots of pictures.

Narrative:

We started walking downhill towards the forest. We first came across a diseased oak tree and then made our way down to cataract creek and then some. It was a windy day but the trees provided protection. A classmate found a tiny salamander as well. Crossing the stream was fun and we made our way to the waterfall after Professor Paul talked about the different species of ferns. Afterwards, we made our way back up the mountain and took a group picture at a scenic spot nearby.
