Supplement: The original is

Are both my guesses correct ?
And, are both grammatically correct?

Answer

Just so you know, 'travelled or perched blocks' is not a standard English phrase. I had to look it up to see what it meant.   It turns out blocks refers to actual stones that have been moved by a glacier. There are no people involved.

Answer

Your guesses are understandable but incorrect in this context. Let’s break it down:
 1. “Travelled or perched blocks” does not refer to people. Instead, it refers to large rocks or boulders that have been moved by glaciers and then left in a new location. These are often called “glacial erratics” in geology.
 2. “Blocks” here refers to physical rocks or boulders, not people.

Explanation:
 • “Travelled blocks” → Rocks that have been moved from their original location by glacial movement.
 • “Perched blocks” → Rocks that are left in an unusual position, often balanced on top of another surface after the glacier melts.

Correct Understanding of the Sentence:
 “The phenomenon of travelled or perched blocks is also a common one in all glacier countries.”
(The occurrence of rocks that have been moved or left in strange positions by glaciers is common in all countries with glaciers.)
