Tributes have been paid to two sisters who died after being pulled from the water at one of Wales' national parks.
Hajra Zahid, 29, and Haleema Zahid, 25, were found in pools on the Watkin Path - which leads to the summit of Yr Wyddfa - also known as Snowdon - on 11 June.
University of Chester said the women "touched the lives of many" since starting master's degrees in international business earlier this year.
An inquest into their deaths is due to be opened on Wednesday by the coroner for north-west Wales.
"The University of Chester community is in mourning for the tragic loss," said the vice-chancellor, Prof Eunice Simmons.
"They touched the lives of many here at Chester – their friends, the cohort on their course and the staff who taught them – and they will be deeply missed."
A former colleague of Haleema Zahid at a telecommunications company in Islamabad, Pakistan, said in a tribute that she was "an exceptionally compassionate, hardworking and kind individual".
Dr Bilal Saeed added she had "touched the lives of many with her warmth, professionalism and unwavering dedication".
Ms Zahid had left the firm to pursue higher education in the UK, he added.
Sheharyar Shahnawaz, another ex-colleague, said Haleema Zahid was an "amazing lady, very lively and energetic, someone you would want in your life".
He said that she became the pillar of her family after the death of her father last year and he had seen her just before she left for the UK when she told him she was "really excited for this new chapter".

Hajra Zahid and Haleema Zahid were studying for a masters degree at the time of their deaths
The Watkin Path is one of the main routes to the summit of Wales' highest mountain.
