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

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 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

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.

Bigelow Range

After a summer of hiking and the completion of my Adirondack 46, I still have an itch to get out hiking.  This weekend’s blue-sky weather beckoned, despite the unseasonably hot and muggy conditions (highs in the 70s and 80s in late September?), so I turned my attention to the Appalachian high peaks of Maine and headed for the Bigelow Range.  My campsite, in the col between its two major peaks, allowed me to enjoy sunset on the western peak and sunrise on the eastern peak, followed by a beautiful ridge walk. Read on, and check out the photo gallery.
