Hoover Dam

Just a few miles east of Las Vegas lies Hoover Dam, one of the USA's most famous engineering projects.  It was built during the great depression to provide a reliable supply of electricity to Nevada, Arizona and California.  It's also a major tourist attraction in this part of the USA with around one million annual visitors.

On the way to the dam there is a security check where every car has to be checked over (rather superficially it appeared).  We believe the dam has been identified as a potential terrorist target by the US intel services.  Once we told the officers we weren't carrying any guns they waved us through.

The water level in the lake was very low although the power station ensures a reasonable discharge into the Colorado river.  Apparently the dam spillway has only ever been needed once, during floods in 1983.

After visiting the dam we went for a walk out onto the spectacular Mike O'Callaghan - Pat Tillman memorial bridge which provides a perfect view of the dam wall.  The bridge was built as a Hoover Dam bypass so traffic travelling across the Arizona Nevada border on Route US 93 didn't have to traverse the dam wall.

With climate change and noting the low level of Lake Mead, as we drove back to Vegas we couldn't help wondering about the future of the dam and the electricity it generates.  Unsurprisingly annual electricity generation is down in recent years due to drought and this trend is likely to continue putting pressure on consumption of electricity and water for much of southwestern USA.

Inca Trail day 4

This was the day we would arrive at Macchu Picchu so we awoke with a keen sense of anticipation.   To celebrate the last day on the trail, somehow the chef had whipped up an enormous cake which was served after breakfast.  After a discussion with Marco about the likely weather over the next two days we agreed that it would be best to tour Macchu Picchu as soon as we arrived in mid afternoon rather than wait until tomorrow. Marco assured us that this would mean less crowds and better weather (he was right). We could see the backside of the mountain above Macchu Picchu in front of us as we started out.  Unlike the last two days, today was mainly downhill.  We would have to descend about 1,000 meters and judging by the first part of the morning walk, most of this would be on steep and slippery rocky steps. After alternating descents and traversing along steep hillsides through cloud forest and bamboo groves we reached the ruins of Intipata. Intipata was a very...

Santa Cruz

Unlike our first island hop, Isabela to Santa Cruz was done by boat (see the addendum below for my thoughts about inter island boat travel).  At least the early morning trip was a smooth one.  Luckily we had managed to book an apartment in Puerto Ayora which meant we could do some of our own catering for a change.  By the time we arrived we were slowing down some, we felt we'd seen much of the wildlife the islands offered and frankly, we were exhausted. So we didn't venture too far from Puerto Ayora. One nice place near town we did visit (Eric went twice) was Tortuga bay which was exactly what you would expect a tropical beach to look like.  In fact it had two beaches, one a surf beach and one a quiet cove where you could snorkel with barely a ripple.  There wasn't much wildlife here except a few Iguanas (and one turtle) but the warm water was great for a swim nevertheless. As with San Cristobal we took a taxi trip to the highlands, crawling in Lava tub...

New York: National Museum of Mathematics

When we first came to New York we all wrote down where we wanted to go while we were here. All of us included the math museum (confirms our status as a family of total geeks) so that is where we headed today. On the way we went to the LEGO shop. There was plenty of great Lego art and some pretty cool sets that Samuel hadn't seen before.   The best part was the machine that used a palm print to generate your Lego avatar. Eric: Check out the six pack. Not sure where they got the toupee from though. Samuel is Johnny Depp? Amazingly accurate this one. The famous Flatiron building A nd the math museum? Of course we enjoyed it! It was all interactive with loads of old and new problems to solve. We even got to use maths in an artistic way.  Tessellating Samuel and Eric were most entranced by a floor exhibit which changed periodically but had a range of practical problems. The museum was well populated in the morning with ...
