Our road trip begins as we head west across Texas to the Mexican Border towns.
Pedernales Falls State Park (28-7-14)
We had a difficult re-entry to the US following our “holiday” to Mexico. After the initial threat of deportation, a less vehement immigration officer agreed a further three month visa but on the understanding that we would then leave for a “substantial” period of time. If we were to visit all the National Parks on our initial list, we would have to leave Austin and get on the road pretty quickly. So after celebrating Ian’s birthday, we spent the weekend saying goodbye to friends, packed up the RV and set off on Highway 290 towards Fredericksburg.
On the way we stopped for the night at Pedernales Falls State Park. A clear, spring-fed river flows gently down sloping limestone to create the twin falls which we cycled and hiked to on the first afternoon. Sadly the first three miles of river (the best bit), including the falls area are closed to wading and swimming. The lower river was shallow and pretty uninteresting, but we had a relaxing float at the end of the day.
Next morning we were up early to mountain bike the 6 miles of the Wolf Mountain Trail, so called because it is still home to the “prairie wolf” or coyote. We really enjoyed this track which was a little more technical than we had so far experienced and included a visit to Jones’ Springs at the boundary of the park.
A spectacular natural event at a car lot in Austin
Last night we were invited to join the locals to watch an amazing spectacle in a parking lot behind a “Jack in the Box” fast food outlet in Central Austin. The instructions told us that we should bring a lawn chair, a hat and binoculars!
Until mid-August, Purple Martins come to roost here in just a few trees for the night. After migrating to Brazil for the winter, the birds travel back to their homes in the US and Canada each spring, where they lay eggs, raise their young and prepare for travel. Some birds leave as early as July, whilst others stay as late as October.
When not breeding, the martins form large flocks and roost together in great numbers. We are not talking about a few birds here. We were told that from 8.00pm until sunset, somewhere between 300,000 and 500,000 birds would swarm overhead. This was not to be missed, and so we headed down at around 7.30 in the RV to claim our spot in the car park.
When we arrived, the car lot was already filling up with couples and families, many seated and ready to watch a natural phenomena that has been occurring in this same spot, we were told, for many, many years. No-one seemed to know exactly how these birds “home” back to the same few trees each year and we were fascinated to see how so many would all find space to roost!
