As we very well know that, so we can see sun during 24 hours if we on a high mountain.
Nowhere on Earth is this possible.
Not 1 mountain is tall enough for 24 hour daylight.
The tallest mountains experience the same amount of daylight/nighttime as the deepest valleys.
In fact, ALL parts of Earth experience equal amounts of daylight/nighttime*.
Altitude/height/elevation make absolutely no difference in amount of daylight/nighttime. The only difference is a tall mountain would see the sunrise earlier, but it would also set later. Meaning amount of daylight is equal to surrounding base of mountain.
I want to just keep reiterating this over and over. All parts of Earth have equal parts night and day when you add it all up.
You want to know why??? It's a spinning sphere.
