The state of Utah in United States is home to many beautiful National Parks, and Bryce Canyon National Park ranks as one of most magnificent and awe inspiring.

15 million years ago earth in this region began to shift, forming a series of plateaus. The Paunsaugunt is an extensive plateau, with Paria River gradually eroding away edge to form Bryce Canyon.

The rock in Bryce Canyon is composed of layer after layer of sediment deposits, deposited millions of years ago when area was at bottom of a lake. Now Paria River has exposed layers, allowing a detailed history of lake to be determined.

The Park itself was established in 1924, and was named after an early settler in area, Ebenezer Bryce. He emigrated from Scotland, married a local girl then moved southwards in stages, building sawmills as he went.

In mid 1870s he reached Paria River, where he and his family settled for a number of years. It was at this time that Bryce made his immortal comment about Bryce Canyon - he called it "one hell of a place to lose a cow".

The area remained basically undiscovered by European tourists, first guest houses only being constructed around time when park was officially established.

Luckily this has led to Bryce Canyon being an area of largely unspoiled beauty, as well as enormous scientific value of historic information trapped in its pinnacles and spires.

The canyon is by no means a stagnant place - rim recedes by an average of about a foot every 50 years, and in this ever changing scene it is water that plays most vital role in shaping and eventual destruction of magnificent scenery.

Because rock was laid down in layers, there is a variation in hardness of rock formed. When water runoff trickles across rock, some areas erode rapidly whereas others hold firm.

This variation in erosion speed causes formation of pinnacles, or "hoodoos" of stable rock. In some places water seeps down through cracks and eats out holes beneath surface. When side rock erodes away, an archway is left behind.

Mount Kenya is an awe-inspiring spectacle that dominates central Kenyan highlands. It is perhaps understandable that Kikuyu people who reside on its lower slopes thought it fit for Gods' abode. And it inspires people in strange ways. In 1943, Felice Benuzzi, an Italian prisoner of war held at Nanyuki at base of mountain, and two companions, escaped and attempted to scale summit. With just a few handmade climbing tools, he managed reach Point Lenana, mountain's third highest peak.

But Benuzzi was at least an accomplished mountaineer. In 1988, Mount Kenya Rescue Team discovered and retrieved an elder of Meru people way up at chilly heights of Peak Nelion (5,188 m). Only experts, with proper equipment and guides reach Nelion. He appeared unaware of feat he had accomplished and was perturbed by fuss his rescuers raised. He explained his mission was "going to God". He was kitted in a manner you will not see recommended in any guide book- in a single blanket and open sandals. The animals do weird things too: a few years ago, frozen bodies of a leopard and colobus monkey were discovered at Nelion.

Mount Kenya is located 180 km to north of Nairobi. The mountain falls within Mount Kenya National Park. The park is made up of a protected area above 3,200m altitude, together with two small salients reaching to 2,450 m along Naro Moru and Sirimon trails. It was set up in 1949 and covers an area of 715 sq km. It is further surrounded by Mount Kenya National Reserve, which extends over 2,075 sq km. The park has distinction of being simultaneously a World Heritage Site and an International Biosphere Reserve.

The mountain is made up of three main zones: rocky peak region, afro-alpine moorland with its scattering of giant vegetation, and extensive lower slopes covered in mountain forest and bamboo. The astonishing ecological diversity is one of attractions of this giant. The ecological processes that have brought about afro-alpine flora in particular intrigue scientists. There are 81 species of plants here that are found nowhere else in world.

In lower forest zone, there is plenty of wildlife including buffalo, elephant, sykes monkey and bushbuck. The animals are however generally difficult to see. Further up, animals are even scarcer though hyena, leopard, buffalo and civet cats have been sighted. The only animal you are likely to see in upper alpine zones is rock hyrax. Though it is size of a domestic cat, it resembles a rat more. The seemingly humble rock hyrax has some powerful relatives in animal kingdom and it counts elephant as its biological kin.

The mountain attracts over 30,000 enthusiasts every year. Point Lenana (4,985 m), so-called trekkers peak, can be reached by any reasonably fit and suitably prepared person. The summit has twin peaks of Batian (5,199 m) and Nelion (5,188 m), and is accessible to only those with technical mountaineering and rock climbing experience. This mountain is not an easy one to conquer and each year not more than 100 climbers make it to twin summit peaks. Mount Kenya is in fact considered to be more technically challenging than higher Kilimanjaro (5,894 m). But those who make it to top experience some of Africa's finest rock and ice climbing.

The mountain has very many fans and especially fascinates technical climbers. The author and mountaineer, Rick Ridgeway - author of Seven Summits, declares that of all worlds' mountains this is his favourite. Halford Mackinder planned and led first expedition on record to reach summit in 1899. But if Meru elder mentioned above is anything to go by, locals must have long ago been to mountaintop. The Mackinder trip was a great success and his party discovered many species of animal and plant life then unknown in Europe. A new species of eagle owl, for example, was first recorded by this expedition and subsequently named after Mackinder.

Though Mount Kenya is practically on equator, you will find snow and ice and even glaciers. However, in one hundred years since Mackinder conquered mountain, number of glaciers has dropped from 18 to only 7 that remain today. The culprit for this is global climate change that has accelerated in recent years. Scientists tell us that during ice ages large glaciers reached below 3,000 m. Today largest glacier is Lewis Glacier at 4,600 m. The continuing retreat of glaciers is expected to have a negative impact on downstream eco-systems, not to mention scenic appeal of mountain.

Mount Kenya is source of Tana River- Kenya's biggest river- and was for many years seen as an inexhaustible water fountain. Not any more- loss of glaciers and forest cover has brought this assumption into disrepute. The loss of forest cover is particularly worrying, because it is avoidable. How to save forests of Mount Kenya has long engaged environmentalist Wangari Maathai-the 2004 Nobel Peace Prize winner. She was born on lower slopes of mountain and has in her lifetime witnessed changes up at mountain.
