A mountain of disappointment

Very iterally.

Back in the early 1800s, a pair of Indigenous persons travelled a mountainous peak. What they saw, was disappointing.
With no official name in place yet, the pair decided they would not mess up their amazing opportunity to name this peak “Mount Dissapointment”

Which is exactly what they did.
according to Wikipedia “Mount Disappointment is one of Melbourne’s most accessible forest areas, with many recreation activities available including the 40 km (25 mi) long Mount Disappointment Forest Drive, various walking tracks, picnic area and camping sites.”

The forest is managed by the Victorian Department of Sustainability and Environment.

To be honest, it really ain’t that bad.
