Hike Details

The main driver for today’s hike was to see the Gleno Dam. Ever since we saw a photo of it several years ago - part of it missing and in an impossible but beautiful looking setting - we knew we would go see it. Add to that the necessity of place to eat (because we walk to eat) and the hike to Rifugio Tagliaferri via Val di Gleno was born.

We were advised not to take Sentiero 411 – Sentiero 410 (via Val di Gleno) to the Rifugio Tagliaferri but rather to take the more popular Sentiero 413 (via Valle del Vò). We were glad we stuck to our original idea because Sentiero 411 seemed to be the less popular route, which for us was a good thing. And, Sentiero 411 is about the same in time and distance.

The hike worked out like this:

1. We started in Vilminore and took the shuttle up to Pianezza.
• If you are off-season, you can try and drive up to Pianezza and park.
• Or, you can start walking in Vilminore.
2. From Pianezza, we took Sentiero 411 to the dam.
3. From the dam, we picked up Sentiero 410 to Passo Belviso.
4. From Passo Belviso, we picked up Sentiero 321 to Rifugio Tagliaferri.
5. Lunch at Tagliaferri.
6. Reverse direction and head back to Pianezza/Vilminore.

A note on the shuttle bus:

We started in Vilmimore and parked the car in one of the many free lots. From there, we took a small shuttle (navetta) up to Pianezza, where we started hiking. You can also hike right out of Vilminore by walking up to Pianezza following the road or taking one of the trails marked “Diga del Gleno”. We walked back down the road from Pianezza to Vilminore at the end of the day and it wasn’t bad. The shuttle costs 4 euros one way. We purchased tickets at Bar Imperial and the shuttle stop is at the municipio across the street from the bar. Why take a shuttle instead of driving up to Pianezza? During the summer months, only residents are allowed and you must take the shuttle. Off season, and you don’t need to worry. On our way up to the dam – around 8:00 am – it wasn’t crowded at all, that is, no people on the shuttle, few hikers, and few people at the lake except for some overnight campers. When we returned in the afternoon, the tents on the lake where gone and replaced by many families up to enjoy Sunday at the lake. And there was a waiting line for the shuttles back going from Pianezza down to Vilminore, which is why we walked.

On this hike it’s hard to get lost, but in bad weather, uncertainty, or just plain wanting to know how far to go to the next landmark, you can download the GPX tracks from the CAI links included in this post and use them in MAPS.ME. We’ve found that you sometimes need to convert tracks from the CAI Bergamo site from GPX to KML to get them to load in MAPS.ME.

There was a small refreshment stand / bar on the lake. After that, there is nothing until you reach Rifugio Tagliaferri. The Rifugio is named for Nani Tagliaferri, the first president of the Valle di Scalve chapter of CAI. Tagliaferri, the person, disappeared in 1981 in the glaciers of the Peruvian Andes. Tagliaferri, the rifugio, was inaugurated in 1985.

The Gleno Dam

The central part of the dam collapsed early on the first of December 1923. From 1535 m (5,036 ft), the water rushed out finding its way to the north end of Lago Iseo at approximately 186 m (610 ft) and killing more than 350 people along the way. What went wrong? The dam had just been completed not more than four months before, but there were warning signs along the way from the quality of the cement and reinforcement used to a change in the type of dam permitted and type build. The last point is interesting because the Gleno Dam was permitted as a gravity dam but during construction which was changed from a gravity dam to a multiple-arch dam. A gravity dam relies on its weight to hold back water. A multiple-arch dam uses less concrete and relies on distributing the force of the water to the arches (buttresses) on both sizes of the dam. It’s these arches that give the Gleno Dam its captivating look as if it were of ancient Roman origin. But sadly, it wasn’t or else it would probably be standing. Cost cutting to save concrete and reused scrap metal from WWI inside the concrete likely led to its collapse.

However, a very thorough analysis (in Italian) Il crollo della Diga di Pian del Gleno: Errore Tecnico? suggests that situation was much more complicated and that the dam was built to specifications of the time. Further, many of the allegations of bad cement or reused scrap metal may not have much to do with the collapse. The analysis also discusses the evidence supporting the possibility of sabotage, including the theft of dynamite two days before the collapse. The court case ran from 1924 to 1927 and found the owners and many others involved guilt, with compensation for damages to the survivors.

An interesting point raised in the report is that the dam was planned to provide energy for a cotton factory. At one time, the valleys above Bergamo were filled with industry run by the water. Today, as you drive up the valleys, in this case Val Seriana and then into the Val di Scalve, you can’t help but notice along the road (which stays close to the river) the hulking abandoned factories that speak to that past. Some of the structures are beautiful examples of industrial architecture.

Another point from the analysis was this disturbing sentence: “L’ondata fu preannunciata da un violento spostamento d’aria che iniziò l’opera di distruzione, strappando le vesti a chi si trovava all’aperto, seguita dalla massa d’acqua che, dopo aver devastato I centri abitati della valle, si esaurì nell ago d’Iseo.” The translation is this: “The wave was preceded by a violent rush of air before the destruction, ripping off the clothes of those who were outdoors. The rush of air was followed by a mass of water that, after ravaging the population centers of the valley, found its way to the top of Lago Iseo.” The ripping-off of the clothes part stuck in my mind. In the report, there is a picture of the victims laid out in a room - presumably by the responders to the disaster - some with bits of cloth or twigs and branches discretely placed over private parts.

To this day, we’ll never know what caused the dam to collapse.
