I See the Moon

I see the moon,

The moon sees me,

Shining above the old oak tree.

Please let the moon,

That shines for me,

Shine for the one I love.

Edgewood Rocks! (Geology)

Geology is key to the diversity of habitats and the success of Edgewood as a nature preserve. Because of the specialized geologic makeup of this 467 acre site, rarely seen native California wildflowers and other plants have maintained a toehold.

Because of Edgewood geology, animals dependent on plants that grow in this specialized area find a home.

Because of Edgewood geology's contributions to rare and endangered plant and animal communities, local citizens preserved this area as a natural space for future use by plants and all animals (including humans)


Key Components of Edgewood Geology

1. Tectonic Plate* Boundary
   
   • The North American Plate
   Edgewood lies along the western edge of this formidable slab of rock, that floats over the Earth's mantle in much of North America.
   • The Pacific Plate
   This plate is the largest of the tectonic plates. Though it's not beneath Edgewood, it does provide a foundation for the Santa Cruz Mountains, which can be viewed from the western side of the park.
   • The San Andreas Fault
   This fault marks the border between the North American and Pacific plates. Evidence of this junction can be seen in the valley covered by the Crystal Springs Reservoir, beyond the 280 freeway on the western side of Edgewood preserve. Many earthquakes in the area are due to movement of these two great plates along this boundary.
2. Rock Types
All the rocks at Edgewood started out on the ocean-floor. They arrived in the preserve via subduction**, the movement of one tectonic plate beneath another, and were later recycled as continental crust. Much of the rock within the park is part of the Franciscan Complex.
1. Serpentinite/Serpentine
A particularly significant rock in the Franciscan Complex when it comes to the success of Edgewood meadow and chaparral plants, and the survival of the Bay Area Checkerspot Butterfly. Serpentine rock, and the soils and plants it contributes to, are found on the Clarkia and Serpentine Loop Trails. Only 1% of CA rock is serpentine. It breaks down into soils that produce masses of flowers, and other plants adapted to it's unique composition.

2. Other Rocks in the Franciscan Complex
These rocks include greywacke, melange, and greenstone. They contribute to soils, and therefore plant and animal life, in the central ridge (Ridgeview Trails) area and upper oak woodlands of the popular Sylvan Trail.

3. Whiskey Hill Formation
This sandstone occurs in the woodland area of Old Stage picnic grounds. It extends into areas beyond the preserve, notably in Pulgas Ridge Open Space (Dogs not allowed at Edgewood are permitted at Pulgas Ridge!). Handley Rock , a popular local rock-climbing site and an intriguing view from Edgewood, is composed of Whiskey Hill

Getting neighborly at El Palacio Cristal, El Parque de Buen Retiro, Madrid

My favorite activity in Madrid was walking in the wonderful big city park, El Parque de Buen Retiro. I walked there every day. I chose the hotel I went to, Hotel Agumar on Calle de Reina Cristina, because I saw that park on the map nearby. I have really enjoyed locating near parks in other big cities, with which I was unfamiliar. I’m used to walking a lot at home. Not only is it nice to have a great big swath of shady green, I like getting to see people out strolling, biking, skating and enjoying the company of their pets and children. At home I have a lot of casual interactions with pets and people in my own neighborhood park and this was a similarly comfortable way to interact with people in Espagna.

The spot I returned to most often in the park was the turtle pond by El Palacio Cristal - a beautiful building if ever there was. It was fun going and sitting on the steps there in the evening, to watch the turtles and have low-key chats with children and adults. That's when I really felt a part of the community. And, unlike in the restaurants, when people started to smoke, I could move!
