I am planning to do a 3-day hike combined with multiple via ferratas this summer in the Brenta Dolomites in Italy. I haven't done the big research yet, but from looking at the (hiking) map I can see that I will need to cross a couple of (what looks like) very small corners of a glacier. I estimate the crossings to be no longer than a few hundred meters. How serious those glacier crossings could possibly be? Is it likely that there would be cracks big enough to fall in at the edge of a glacier? Can there be snow covered cracks in July/August at around 3000 meters? Is it likely that the ice would be steep at the very corner of a glacier?
I do not have any glacier crossing experience beyond stepping onto some in touristy galcier watching spots (in Canada, Island). And I do not want to bring too much unnecessary equipment. But I could get crampons, I will have a harness, hiking sticks, at least one other person with me, and I can bring a 20-meter-long rope. I would absolutelly not want to carry an ice axe though.
I will of course do more research before I go, and I have sufficient experience with hiking and via ferratas. So what I would like to know, is really just an estimate on how challenging such a short galcier crossing could possibly be.
