This small, 2019 Canadian definitive is a very nicely printed, photographic view of Smoke Lake in Algonquin Provincial Park (ON). The Park looks to be a great vacation spot for someone who likes to canoe. Close-up pic shows the stamp's bilingual microprinting.

From portagestore.com website, "You can spend days, if not weeks...in Algonquin Park. There are over 1600 kms. of canoe routes and hundreds of lakes and waterways, and it's all flat paddling. Your journey is going to include portages which are a part of every route in the park."

Here are three stamps featuring Lake Rotomahana, New Zealand. The first two stamps show features of the pre-1886 site. They are the 4d. value of 1898 (S.G. #252) depicting the White Terrace, and the 9d. value of 1898 (S.G. #256) showing the Pink Terrace.

The Third stamp is an issue of private courier Fastway Post New Zealand Ltd. It shows post-1886/present-day Lake Rotomahana and its steaming cliffs.

From Wikipedia, "It is immediately south-west of the dormant volcano Mount Tarawera, and its geography was substantially altered by a major 1886 eruption of Mount Tarawera...The Pink and White Terraces were a natural wonder on the shores of the lake before the 1886 eruption. They were considered to be the eighth wonder of the natural world and were New Zealand's most famous tourist attraction during the mid 19th century, but were buried or destroyed by the eruption."

These two 50c (domestic rate) stamps of Fastway Post New Zealand, Ltd. the same photographic view of Lake Okareka, with different cropping and color printing.

From Wikipedia, "Lake Okareka is one of four small lakes lying between Lake Rotorua and Lake Tarawera, in the Bay of Plenty region of New Zealand's North Island...The lake has a circumference of six miles (9.7 km) and lies about 60 meters above Lake Tarawera. Its outlet flows underground for half a mile and forms the Waitangi waterfall. In fact, the Okareka Lake seems to be connected with the Tarawera by underground channels."
