What blessing do we say when we see mountains, deserts, or great rivers?
Over mountains, deserts, and great rivers — the vast, enduring shapes of the world — we say the blessing that Hashem makes the work of creation, the very same blessing said over lightning.
One blessing for the great works of creation (Berachot 54a)
The Talmud, in Berachot 54a, teaches that when we see the great and lasting features of the world — towering mountains, wide deserts, mighty rivers — we bless Hashem as the One who makes the work of creation, עושה מעשה בראשית. It is the same blessing we say over a flash of lightning: both are the handwriting of the same Maker.
Why the same words
Lightning lasts a heartbeat; a mountain has stood for ages. Yet the tradition gives them one blessing, because both stop us in the same way — with the sense that this was made, and we are standing inside someone else's work. Naming it is a mitzvah (commandment) of attention: it keeps wonder from slipping past unspoken.
What to do
When you come upon a mountain range, a desert, or a great river — something that genuinely stirs you as one of creation's wonders — say the blessing 'oseh maaseh bereshit,' that Hashem makes the work of creation. For a view you see every day the custom differs, so this is meant for the moment that truly catches you. When you are unsure about a particular sight, bring it to your rabbi.

Barkai (the blessings of the day; the sky and place tell you the moment) reads where you are standing, so when the landscape opens up, the blessing is already there to meet it.
