Yosemite

We took a brief family vacation in Yosemite Park, late June 2018. The first day we walked the Mariposa Grove of giant sequoia trees and visited the Glacier Point overlook. The second day we hiked a loop up to Lower Yosemite Falls, then up to Vernal Falls via the Mist Trail. The third day we walked from Glacier Point down the Panorama Trail, past Illilouette Falls, Nevada Falls, and Vernal Falls; later we caught sunset from Tunnel View point. The final morning I snapped sunrise at Valley View, and later we visited Bridalveil Fall, Yosemite Chapel, Sentinel Bridge, and Valley View, before driving back to San Francisco. Hot and crowded, but beautiful!

Just back from a brief family vacation in Yosemite National Park. Somehow, I’d never managed to visit this gem of the park system, and have long been eager to do so.  John is interning in silicon valley this summer so it provided the perfect excuse for the rest of us to hop out there to spend three days in the park.  We were fortunate to have clear, sunny weather throughout – though it was hot (over 90° every day) and crowded.  It was nonetheless a great place for me to test a new batch of camera gear.

Zion from sunrise to sunset

I had the great pleasure of spending 24 hours in Zion National Park, as a quick respite from the hustle and bustle of work life and a conference in Las Vegas.  (After a brief visit to Zion in 2014, I knew I needed to come back for more!)  I arrived at sunset on Monday and left at sunset on Tuesday, with the aim of doing several hikes and making the best of this photographer’s paradise.  It had snowed over the weekend, so the high cliffs were dusted white, but the weather for my visit portended clear blue skies, a frigid morning, and a warm sunny afternoon.  Read on, and check out the photo gallery. The photos are much more beautiful there!

Mystical India

Two lovely weeks touring northern India with Dartmouth Alumni Travel. Magical! More stories, and photos, in this blog post.

I’ve just returned from India, where Pam and I had the opportunity to host a Dartmouth Alumni Travel group for a two-week tour of the history, architecture, culture, and arts of northern India.   We joined a wonderful group of 12 interesting individuals, and an outstanding tour guide from Odysseys Unlimited, for a bustling tour of Delhi, Jaipur, Ranthambore, Agra, and Varanasi.  I think what struck me most about the agenda was its fascinating mix of the sights (palaces, temples, mosques, etc.) with the culture (villages, markets, families. religion) and arts (dance, music, weaving, pottery, jewelry, stonework, carpets, and even paper).  Read on for a summary of our journey, and for a sampling of the many photos!

Alpine hike in Switzerland

I was in Zurich for meetings and managed to set aside a day for hiking in the high country to the east. Fresh snow and low clouds made for an eerily quite day in the mountains.

I was in Zurich for a day of meetings and decided it would be a great opportunity to go hiking in the beautiful mountains of Switzerland.  So, despite earlier stops in Dallas (for ACM CCS) and Delft (for ACM SenSys) I brought along my backpack, boots, and full winter hiking gear.  On Wednesday morning, after lots of helpful advice from my ETH colleagues, I boarded an eastbound train from Zurich.  Read on for the full story, and check out the photos.

Delft, in The Netherlands

I enjoyed a couple of quick days in the historic district of Delft, The Netherlands, while attending the SafeThings workshop in advance of SenSys 2017.  Although it rained on and off, the picturesque streets and canals were a delight to explore.  I also ducked into the Old Church and New Church (both hundreds of years old), for a peek at their excellent exhibits.  I stayed in Hotel Johannes Vermeer, named after the famous painter, so I was especially interested in those exhibits.   Beautiful town!  See the photos; the one below is from my hotel room (which was a 4th-floor attic!).

Alta-Snowbird traverse

A glorious hike through the high country above Alta & Snowbird ski areas in the Wasatch Range of Utah.

I had the good fortune to be out in Utah to attend the MobiCom conference, held this year at the Snowbird ski resort.  Although late October is the shoulder season, I was nonetheless eager to get out hiking in the mountains above Snowbird.  Wow, was I ever lucky with the weather!  It snowed on the final day of the conference, leaving me to hike through a snowy wonderland on the day after.  See the photo gallery, and read on to hear more about the hike.

Total eclipse

Total solar eclipse viewed from South Carolina.
Total solar eclipse viewed from South Carolina. See the gallery for hi-res photos.

We traveled to northwestern South Carolina to visit family and view the 2017 Total Solar Eclipse – and were totally impressed!  We launched a boat onto Lake Keowee so we could view the partial eclipse and, if needed, relocate to avoid any late-arriving clouds that might obscure our view of the total eclipse.  Darkness arrived suddenly as the moon crept into place, lasting a bit longer than two minutes.  At this point we experienced a 360-degree sunset.

Although I made no specific plans to do serious photography, I found my Nikon D500 with 300mm telephoto was  capable of capturing decent shots of the eclipse, hand-held.  Looking forward to the 2024 eclipse in New Hampshire!
