While it's difficult to pinpoint exactly which national park has the *absolute* most glaciers, Glacier National Park in Montana, USA is often cited as having the most glaciers out of all the national parks in the US.

Here's why:

* Historically: Glacier National Park used to boast over 150 glaciers. While many have retreated and disappeared due to climate change, it still has a significant number of glaciers compared to other parks.

* Large number of glaciers: While the exact number fluctuates, Glacier National Park currently has around 25 active glaciers.

* Focus on glaciers: The park is named after its glaciers, and they are a major feature of the landscape and ecosystem.

However, it's worth noting:

* Global scale: Other national parks around the world, particularly in the Himalayas and the Andes, may have even more glaciers.

* Changing numbers: The number of glaciers in any park is constantly changing due to climate change, so any definitive answer may be outdated quickly.

If you are interested in specific information about the number of glaciers in a particular park, it's best to consult official park websites or contact park rangers.
