Coyote Peak Sign
Me in Santa Teresa County Park, at the interpretive sign on Coyote Peak, 12/6/16. I took most of the pictures, including the panorama, and helped with the sign's design.

Welcome! My favorite hobbies and activities are photography, hiking, biking, computers, geocaching, travel, and travel writing. I've created a number of Web pages on travel and recreation in the San Francisco Bay Area and California. Here you will find links to pages with photos and information on parks, beaches, trails, history, and places to visit.

I'm a retired electrical engineer. I spent over 34 years in the computer disk drive industry, working for IBM, Hitachi, and Western Digital. Among other activities, I am a volunteer photographer and docent for the Santa Clara County Parks & Recreation Department, a docent for the Santa Clara Valley Open Space Authority, and a member of several volunteer and non-profit organizations, particularly the Friends of Santa Teresa Park and the New Almaden Quicksilver County Park Association.

Note that this is entirely a volunteer effort, with no commercial intent or sponsorship. These pages are for information only and are based on my opinions, research, and observations.

I have a Facebook page: If you're on Facebook, you can see my public posts. Please don't send friend requests. For security reasons, I only accept people I already know.

  • My picture of the Casa Grande in Almaden Quicksilver took first place in the non-professional category of the VisualSJ photo contest in 2015. See the Awards section below.
  • My pictures have been used for some of the County Parks' 2015 "Nature is Nearby" Billboards.
  • I taught my annual outdoor photography class at the Bernal-Gulnac-Joice Ranch in Santa Teresa County Park on Saturday November 14, 2015 at 10 am - 1 pm. "Join a Docent for a FREE outdoor photography workshop. Learn how to choose and use a camera, how to take better outdoor pictures, and about photo composition. Workshop begins with an indoor slideshow, followed by demonstrations and a walk around the historic area to take pictures. Meet at the Bernal Ranch barn, 372 Manila Dr., San Jose." Here are pictures from the class.
  • My pictures were used in an article in Edible Silicon Valley Magazine on Martial Cottle Park: Farm Forward: Planting the Seeds For The Future of Family Farms, January 20, 2016
  • Some of my pictures of the Santa Clara County Parks were used in an episode of the Open Road TV show on NBC Bay Area. See the video on the Parks for Life Challenge, starting at 5:41 to 6:05.
  • I joined the Friends of Santa Teresa Park in leading hikes in April at Santa Teresa Park:

  • Measure A was on the June 2016 ballot. It renewed the Park Charter Fund, which allocates a fixed percentage of Santa Clara County's budget to fund the County Parks. It is not a tax, but an earmark that guarantees that the parks will get their fair share of the budget. It provides a reliable source of funding (though not a fixed dollar amount) for the County Parks, which allows them to maintain a high-quality park system and do long-term planning. The ballot measure also increases the percentage of the fund allocated for park development to allow them to do park improvements and open new parkland. My pictures were used as part of the "Yes on A" campaign. Measure A passed with about 78% yes votes. It only needed just over 50%.
  • On 6/26/16, I was featured on an episode of "Open Road With Doug McConnell" on NBC Bay Area. See below for details. Below is a screenshot from that episode, with me being interviewed by Doug McConnell:

  • I have been making a Coronovirus Blog, with information, links, and statistics about the COVID-19 virus, how it's affected us in Santa Clara County, and how it's affected me with events cancelled. On 3/16/20, the Santa Clara County Public Officer issued a stay-at-home order to everyone in the County except for those providing essential needs. On 3/19/20 Governor Gavin Newsom issued a similar order to everyone in the state of California, with no end date. However, people are still allowed to go outside and get exercise, which includes hiking and biking in the parks and preserves in Santa Clara County. I have a document called "Trail Usage Tips During the Coronavirus Crisis," with tips about safe social distancing to prevent spread of the virus while using the trails.
  • I had intended to teach another outdoor photography class/wildflower hike at Santa Teresa Park in May, 2020, but it was cancelled due to the COVID-19 crisis. The Friends of Santa Teresa Park and I were planning to lead another pre-Mother's Day hike in Santa Teresa Park the day before Mother's Day. It was also cancelled. All park group events and volunteer activities in the County Parks and Open Space Authority preserves have been cancelled or are on hold indefinitely. Instead, I have been solo hiking, taking pictures, and posting them on Facebook and Next Door. I also have been watching videos and attending Zoom conferences from various organizations, such as Saved By Nature, the Open Space Authority, and the Santa Clara County Parks
  • Starting around May of 2021, I started going to park events organized by private groups, like Saved By Nature, the BioBliltz Club, and Keep Coyote Creek Beautiful. (See 2021 Facebook albums.) 
  • I haven't been able to teach in-person photo classes since the pandemic started. However, I gave Zoom photo classes in 2 parts for the California Native Plant Society, Santa Clara Valley Chapter, as part of their monthly photo-sharing group. I have been participating in the group and showing plant and flower pictures from local parks and preserves.
  • On 9/27/21 at 12 pm, there was an online forum called "Shining a Spotlight on the Coyote Creek Watershed." It was part of the regular "Peninsula-South Bay Watershed Forum."

I showed pictures from Palassou Preserve, Coyote Lake, Anderson Lake, the Coyote Creek Parkway, Coyote Valley OSP, North Coyote Valley Conservation Area, Coyote Ridge, Santa Teresa Park, Hellyer Park, and more, all the way to the Bay. Here's my Powerpoint slideshow (68MB PDF).
  • On 10/3/21, I led a hike at McClellan Ranch Preserve/Blackberry Farm Park on the Stevens Creek Trail in Cupertino for the California Native Plant Society Santa Clara Valley Chapter.

In July, on the way back from Mt. Madonna County Park, I saw a new trail next to the Hecker Pass Highway. I explored it and discovered a new trail, which led to an existing trail. I made 4 albums about it. This is the first: Exploring the New Hecker Pass Trail in Gilroy, Part 1, 7/31/21.
    Hecker Pass Trail

  • On 10/16/21, I led a tour of the Master Gardeners' Parcel at Martial Cottle Park for the California Native Plant Society's Santa Clara Valley Chapter. The Master Gardeners had an open house that day. It was similar to their open house they had during the "Explore Martial Cottle Park" event on 10/2/21.

  • On 4/23/22, the Santa Clara County Parks held their 27th annual Volunteer Recognition event. It was held at the Bunea Vista Group Picnic Area in Hellyer County Park. I was recognized for achieving 14,000 lifetime volunteer service hours. That gave me one of the highest number of volunteer hours. I was recognized for 14,500 lifetime volunteer service hours at the Volunteer Recognition event on 4/15/23 at Hellyer County Park and 15,000 lifetime volunteer service hours at the Volunteer Recognition event on 4/23/24 at Martial Cottle Park.

  • On 5/13/23, the Saturday before Mother's Day, I helped to lead a hike in Santa Teresa County Park with the Friends of Santa Teresa Park. The event was called "Where Nature & History Collide" The hike was on the Fortini, Mine, and Stile Ranch Trails and included stories about the history of the area, along with the natural history of the park. While others talked about the history of the area, I talked about the wildflowers and the importance of serpentine soil  See the flyer for details. Here are pictures of the hike.

    I helped to lead the hike again on 5/11/24. It was called the "Mothers and Flowers Hike. 
    Here are pictures from the hike.

  • On 5/19/24, I led a hike at Spreckels Hill, which is a 215-acre part of the 953-acre North Coyote Valley Conservation Area south of San Jose. It is owned by the Santa Clara Valley Open Space Authority (OSA) and is normally closed to the public, except for special events (like today's) or by request. The purpose of this hike was to teach some tips about photography and introduce visitors to the Coyote Valley. The OSA has a photo contest. They are looking for pictures of the Coyote Valley. Here are the contest details. We walked along Fisher Creek and went up to the top of Spreckels Hill to get panoramic views of the Coyote Valley. Along the way, I talked about photography techniques and talked about the Coyote Valley, its history, its natural features, and efforts to preserve it. Here are pictures from the hike.

What's a BioBlitz? "A BioBlitz is an event that focuses on finding and identifying as many species as possible in a specific area over a short period of time. At a BioBlitz, scientists, families, students, teachers, and other community members work together to get an overall count of the plants, animals, fungi, and other organisms that live in a place." Participants use the iNaturalist app or website to record and upload observations. Here are local BioBlitz results on iNaturalist: South Bay BioBlitzes. See here for BioBlitz events.
BioBlitzes have occurred in many parks and open space preserves. They are listed above by their location. This section collects them into one place: Outdoor Photography

Some of the documents mentioned below are no longer available online. I've removed the links, but kept the reference. Where possible, I've downloaded the documents to one of my websites and linked to them.

I've received a number of awards over the years. Here's a sample of them:

Note on Geocities migration: Geocities was a web hosting service that was founded in 1994. They offered free web hosting for small web pages. Many of my web pages, including the predecessor of this one, were on Geocities. The webpages included, which was my main page, geocities,com/santateresapark, bayareaparks, almadenqs, santateresahills, stpfriends, and some others. Geocities was acquired by Yahoo! in 1999, but they shut it down in October 2009. I migrated most of my webpages to this website or other websites that I control. While the links below work, the links on the pages that they are linked to most likely don't work. Here are my old Geocities websites and their new locations, including some archive sites for the pages that haven't been migrated:

Bay Area Back Pages

For many years, I had a website on Prodigy called "Bay Area Back Pages." This is what it said:
Bay Area Backpages - Visit my first webpages on Prodigy, started in 1997, once featured on TV, on travel and outdoor activities in the Bay Area. It has pages on parks, hiking, camping, biking, beaches, swimming, museums, playgrounds, views, and information about places in the Bay Area and other parts of California. There's also a technical section on scanners. Prior to these webpages, I was a frequent contributor to Prodigy and other travel bulletin boards, and I found I was frequently answering the same questions over and over again. These pages gave me a means of having the information available permanently. Because of space limitations, I have not been able to expand these pages, so some have been supplanted with pages on this site.

On June 1, 2011, AT&T terminated the Prodigy Personal Web Pages without warning (to me, at least). All my Bay Area Back Pages at are now dead. I may revive some of them here, but it will take time. Many of those pages are very old and are in need of upgrading. In the meantime, you can still find the home page on this archive. See here for the history of Prodigy.

I attempted to re-create Bay Area Back Pages on this website, but not everything is working yet. Here are the major pages for my migrated Bay Area Back Pages. Note that many of these pages date from the 1990's, so they are not up-to-date. The links are most likely stale. Some things never change, so much of the fundamental information is still valid. Just don't expect the links to work.
The information in these web pages was accurate to the best of my knowledge at the time the pages were written, but is not guaranteed to be accurate or current. Factors such accessibility, conditions, rules, ownership, directions, etc., can change without notice. Readers are responsible for finding out the latest conditions before venturing out. The information on these pages should not be treated as official, but as private opinions and observations. These pages are non-commercial and not officially associated with any company or agency.

Note on Dead Links:
Links go dead faster than I can fix them. The older the web page, the more likely the links will be dead. All of these web pages are volunteer efforts, done in my spare time. I don't have time to constantly go back to check and refresh links on old web pages. However, if you are looking for some specific information, send me an e-mail, and I can see what I can do to answer your questions.

Note on Link Exchanges:
Sorry. I don't have time, so please don't ask.
I do not accept commercial link exchanges.
