Grand Canyon · United States
Read the canyon in layers
The Grand Canyon exposes a long and complex rock record. The age of those rocks is not the same question as the history of the canyon cut into them. Keeping those two ideas separate is the first useful step.
From a viewpoint, follow one layer across the landscape. Notice how its expression changes between cliff and slope, light and shadow. Then turn to the NPS geological explanation for the processes and uncertainties behind what you see.

Pick one visible layer and trace it as far as you can. Separate an observation, such as a change in colour, from an interpretation about the environment in which it formed.

Fiordland National Park · New Zealand
Look for the work of ice
Fiordland’s steep inlets and mountain landscapes belong to a region shaped by repeated glaciation. Present-day water occupies forms with a much longer history.
The shape of a valley can suggest a process, but a single photograph rarely proves the whole story. Compare the large form with smaller present-day features: waterfalls, vegetation and the way light reveals the walls. The landscape is still changing after the great ice has retreated.
Try this way of looking
From an authorised viewpoint or boat route, compare the scale of the valley with a waterfall or tree-covered slope. Use that contrast to think about time as well as size.

Iguazú Falls · Argentina & Brazil
Watch the water, read the forest
At Iguazú, moving water is impossible to ignore. The surrounding Atlantic Forest adds another scale of attention: shade, moisture, vegetation and wildlife around the visitor route.
A memorable visit can alternate the wide waterfall view with a few quiet minutes looking away from it. The falls are not an object displayed in empty space. Their environment is part of what makes the encounter remarkable.
Try this way of looking
From the designated paths, spend one minute on the broad view and one minute on a small patch of surrounding forest. Record the difference in sound, movement and scale.
